Question

The numbers a,b,c and d are distinct positive integers chosen from 1 to 10 inclusive.

What is the least possible value a/b + c/d could have ?

Answer 1

Answer: a/b + c/d = 14/45 ≈ 3.111

Explanation:

a / b + c / d may have the smallest value, for example, if:

a = 1

b = 9

c = 2

d = 10

Therefore, we get:

1/9 + 2/10 = 14/45 ≈ 3.111
