Answer:

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)
