What do you add to 3 (3)/(8) to make 7?​

Question

What do you add to

`3 (3)/(8)`
to make 7?​

Answer 1

`(29)/(8)`

Explanation:

3
`(3)/(8)` equals to
`(27)/(8)`, then we can write out the equation:

`(27)/(8) + x = 7`
then subtract
`(27)/(8)`on both sides of the equal sign,

`x = 7 - (27)/(8)`

and then we calculate x

`x=(56-27)/(8)`

`x=(29)/(8)`

Thus the answer is
`(29)/(8)`
