Question The price of 1 kg of oranges is ₹ 56.50. What is the price of 2.250 kg of oranges? Can we write 56.50 as 56.5 and 2.250 as 2.25 and multiply? Will we get the same product? Why?
Price of 1 kg of oranges = ₹ 56.50 Price of 2.250 kg of oranges = 56.50 × 2.250 = \(\frac{5650 \times 2250}{100 \times 1000}\) = \(\frac {12712500}{100000}\) = ₹ 127.125 Now 56.5 × 2.25 = 127.125 Hence, we will get the same product. The zeroes at the end of a decimal do not change its value. As we saw, 56.50 is the same as 56.5, and 2.250 is the same as 2.25. Hence, the product of the two numbers will be the same.
