Question

What number should be added to 7/12 to get 4/15?​

Answer 1

Explanation:

Let the number = x.

We are trying to find out what number (x) we would need to add to 7/12 to get 4/15

`(7)/(12) + x = (4)/(15)`

Subtract 7/12 from both sides.

`x = (4)/(15) - (7)/(12)`

We need to make the denominators of the fractions the same.

`(4)/(15) = (16)/(60)`

`(7)/(12) = (35)/(60)`

So,

`x = (16)/(60) - (35)/(60) = - (19)/(60)`
