Question

Suppose you select a number in the interval from 1/2 to 3/4 and a number in the interval from 3/4 to 1 1/4 . What is the least possible sum for these two number

Answer 1

1 1/4

Explanation:

The least sum is the sum of the least numbers. The smallest number you can choose from the first interval is 1/2; the smallest number you can choose from the second interval is 3/4.

The sum of 1/2 and 3/4 is 5/4 = 1 1/4. This is the smallest possible sum for the numbers described.
