Question 12

Write a program to read two lists num and denum which contain the numerators and denominators of same fractions at the respective indexes. Then display the smallest fraction along with its index.

Solution
num = eval(input("Enter numerators list: "))
denum = eval(input("Enter denominators list: "))

small = 0.0
smallIdx = 0

for i in range(len(num)):
    t = num[i] / denum[i]
    if t < small:
        small = t
        smallIdx = i

print("Smallest Fraction =", num[smallIdx], "/", denum[smallIdx])
print("Index of Smallest Fraction =", smallIdx)
Output
Enter numerators list: [1, 3, 1, 7, 3]
Enter denominators list: [2, 4, 4, 13, 8]
Smallest Fraction = 1 / 2
Index of Smallest Fraction = 0
Answer

num
=
eval
(
input
(
"Enter numerators list: "
))
denum
=
eval
(
input
(
"Enter denominators list: "
))
small
=
0.0
smallIdx
=
0
for
i
in
range
(
len
(
num
)):
t
=
num
[
i
]
/
denum
[
i
]
if
t
<
small
:
small
=
t
smallIdx
=
i
print
(
"Smallest Fraction ="
,
num
[
smallIdx
],
"/"
,
denum
[
smallIdx
])
print
(
"Index of Smallest Fraction ="
,
smallIdx
)
Output
Enter numerators list: [1, 3, 1, 7, 3]
Enter denominators list: [2, 4, 4, 13, 8]
Smallest Fraction = 1 / 2
Index of Smallest Fraction = 0
