3.4 Decimal Place Value
NCERT In-Text Questions (Pages 61-64)
We can ask similar questions about fractional parts:
(a) How many thousandths make one unit?
(b) How many thousandths make one tenth?
(c) How many thousandths make one hundredth?
(d) How many tenths make one ten?
(e) How many hundredths make one ten?
Solution:
We know that the value of a place in the decimal place value chart becomes ten times at every step moving from right to left, and it becomes $\frac{1}{10}$ times moving from left to right.
Therefore,
(a) 1000 thousandths make one unit.
(b) 100 thousandths make one tenth.
(c) 10 thousandths make one hundredth.
(d) 100 tenths make one ten.
(e) 1000 hundredths make one ten.
Make a few more questions of this kind and answer them.
Solution:
Do it yourself.
Make a place value table similar to the one above. Write each quantity in decimal form and terms of place value, and read the number:
(a) 2 ones, 3 tenths, and 5 hundredths
(b) 1 ten and 5 tenths
(c) 4 ones and 6 hundredths
(d) 1 hundred, 1 one, and 1 hundredth
(e) $\frac{8}{100}$ and $\frac{9}{10}$
(f) $\frac{5}{100}$
(g) $\frac{1}{10}$
(h) 2$\frac{1}{100}$, 4$\frac{1}{10}$ and 7$\frac{7}{1000}$
Solution:
Write these quantities in decimal form:
(a) 234 hundredths
(b) 105 tenths.
Solution:
(a) 234 hundredths can be expressed in decimal form as follows:
234 hundredths = $\frac{234}{100}=\frac{200}{100}+\frac{30}{100}+\frac{4}{100}$
= 2 + $\frac{3}{10}$ + $\frac{4}{100}$
= 2.34
(b) 105 tenths can be expressed in decimal form as follows:
105 tenths = $\frac{105}{10}$
= $\frac{100}{10}+\frac{0}{10}+\frac{5}{10}$
= 10 + 0 + $\frac{5}{10}$
= 10.5

There is Zero Dilemma!
NCERT In-Text Questions (Pages 71-73)
Can you tell which of these (0.2, 0.02, and 0.002) is the smallest and which is the largest?
Solution:
From the decimal place value chart, we see that
0.002 representing 2 thousandths is the smallest, and 0.2 representing 2 tenths is the largest decimal number among the given decimals.
Which of these are the same: 4.5, 4.05, 0.405, 4.050, 4.50, 4.005, 04.50?
Solution:
From the decimal place value chart, we see that
4.5, 4.50, and 04.50 are equal as they represent the same quantity, i.e., four ones and five tenths.
Similarly, 4.05 and 4.050 are equal as they represent the same quantity, i.e., four ones and five hundredths.
But, 0.405 and 4.005 are different as they do not represent the same quantity.
Identify the decimal number in the last number line in Figure (b) denoted by ‘?’
Solution:
By labelling the visualised segment of the number line, we find that the decimal number 3.059 is denoted by ‘?’
Make such number lines for the decimal number:
(a) 9.876
(b) 0.407
Solution:
In the number line shown below, what decimal numbers do the boxes labelled ‘a’, ‘b’, and ‘c’ denote?
The box with ‘b’ corresponds to the decimal number 7.5; are you able to see how? There are 5 units between 5 and 10, divided into 10 equal parts. Hence, every 2 divisions make a unit, and so every division is $\frac{1}{2}$ unit. What numbers do ‘a’ and ‘c’ denote?
Solution:
Since each division between 5 and 10 is $\frac{1}{2}$ = 0.5 unit.
Therefore, the second division after 5, denoted by ‘a’, represents the number 6, while the ninth division, denoted by ‘c’, represents the decimal number 9.5.
Using similar reasoning, find out the decimal numbers in the boxes below.
Solution:
There are 10 divisions between 8 and 8.1, so each division is a tenth part of $\frac{1}{10}$, i.e., $\frac{1}{100}$ = 0.01 unit.
Therefore, the first division after 8, denoted by ‘d’ represents the decimal number 8.01, while the fifth division, denoted by ‘e’, represents the decimal number 8.05.
Further, there are 10 divisions between 4.3 and 4.8, so each division is a tenth part of 0.5 or $\frac{5}{10}$, i.e., $\frac{5}{100}$ = 0.05 unit.
Therefore, the first division after 4.3, denoted by ‘f’, represents the decimal number 4.35, while the fourth division, denoted by ‘g’, represents the decimal number 4.5, and the first division after 4.8, denoted by ‘h’, represents the decimal number 4.85.
Which decimal number is greater?
(a) 1.23 or 1.32
(b) 3.81 or 13.800
(c) 1.009 or 1.090
Solution:
(a) Using the decimal place value chart, we find that:
Both numbers have 1 unit, but the first number has 2 tenths, whereas the second number has 3 tenths.
Therefore, 1.23

(e) 17 – 0.05
(f) 34.505 – 18.1

Estimating Sums and Differences
NCERT In-Text Questions (Pages 76)
Sonu has observed sums and differences of decimal numbers and says, “If we add two decimal numbers, then the sum will always be greater than the sum of their whole number parts. Also, the sum will always be less than 2 more than the sum of their whole number parts.”
Let us use an example to understand what his claim means:
If the two numbers to be added are 25.936 and 8.202, the claim is that their sum will be greater than 25+ 8 (whole number parts) and will be less than 25 + 1 + 8 + 1.
What do you think about this claim? Verily if this is true for these numbers. Will it work for any 2 decimal numbers?
Solution:
The given numbers are 25.936 and 8.202.
Sum of whole number parts = 25 + 8 = 33
Sum of given decimal numbers = 25.936 + 8.202 = 34.138
Clearly, 33

Question 3

What decimal number does each letter represent in the number line below?

Accepted Answer

There are 4 divisions between 6.4 and 6.5, so each division is one-fourth part of 0.1 or $\frac{1}{10}$, i.e., $\frac{1}{40}$ = 0.025 unit.
Therefore, the second division after 6.4, denoted by ‘a’, represents the number 6.45, while the first division after 6.5, denoted by ‘c’, represents the number 6.525, and the second division after 6.5, denoted by ‘b’, represents the number 6.55.

Question 4

Arrange the following quantities in descending order:
(a) 11.01, 1.011, 1.101, 11.10, 1.01
(b) 2.567, 2.675, 2.768, 2.499, 2.698
(c) 4.678 g, 4.595 g, 4.600 g, 4.656 g, 4.666 g
(d) 33.13 m, 33.31 m, 33.133 m, 33.331 m, 33.313 m

Accepted Answer

(a) Using the decimal place value chart, we find that:
Here, the two numbers 11.01 and 11.10 have 11 whole-number parts, but the first number has 0 tenths, whereas the second number has 1 tenth. Therefore, 11.10 > 11.01. The three numbers 1.011, 1.101, and 1.01 have 1 whole number part, but the first and third numbers have 0 tenths, whereas the second number has 1 tenth. Therefore, 1.101 is the greatest among the three. Now, comparing the remaining two numbers, we get 1.011 > 1.01.
Thus, the numbers in descending order are: 11.10 > 11.01 > 1.101 > 1.011 > 1.01.
Similarly, we can arrange the other given quantities using a decimal place value chart as follows:
(b) 2.567, 2.675, 2.768, 2.499, 2.698
Thus, the given quantities in descending order are:
2.768 > 2.698 > 2.675 > 2.567 > 2.499
(c) 4.678 g, 4.595 g, 4.600 g, 4.656 g, 4.666 g
Thus, the given quantities in descending order are:
4.678 g > 4.666 g > 4.656 g > 4.600 g > 4.595 g.
(d) 33.13 m, 33.31 m, 33.133 m, 33.331 m, 33.313 m
Thus, the given quantities in descending order are:
33.331 m > 33.313 m> 33.31 m > 33.133 m > 33.13 m.

Question 5

(a) The decimal number closest to 30.
(b) The smallest possible decimal number between 100 and 1000.

Accepted Answer

Using the digits 1, 4, 0, 8, and 6, we can make:
(a) The decimal number closest to 30 → 40.168.
(b) The smallest possible decimal number between 100 and 1000 → 104.68

Pinto supplies 3.79 L, 4.2 L, and 4.25 L of milk to a milk dairy in the first three days. In 6 days, he supplies 25 litres of milk. Find the total quantity of milk supplied to the dairy in the last three days.

Accepted Answer

The total quantity of milk supplied to the dairy in the last three days = Total milk supplied in the 6 days – Total milk supplied in the first 3 days
= 25 L – (3.79 L + 4.2 L + 4.25 L)
= 25 L – 12.24 L

Since 35.75 kg > 34.50 kg, Tinku has lost weight.
Now, the change in the weight = 35.75 kg – 34.50 kg = 1.25 kg.
