Question

Please anyone help me to solve this question? Thanks in advance. If `x+y=4` for positive integers, what is the smallest value of `1/x+1/y?`

Answer 1

`d. 1`

Explanation:

There are only two possibilities for positive integers that give a sum of `4`.

`1+3=4" "or" "2+2=4`

`1/1 +1/3 = 1 1/3 = 4/3`

`1/2+1/2 = 1`

There can only be one smallest value..

The answer is `1`
