Question

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

Answer 1

Answer:

7/6 is the right answer

Step-by-step explanation:

7/12+x=7/4

x=7/4-7/12

x=(21-7)/12

x=14/12

x=7/6

Answer 2

Answer:

Let the quantity to be added is m.

Thus,

7/12 + m = -4/5

m = -4/5 - 7/12

Take GCD, make the denominators equal and then add 'em up.

m = (-48 -35)/60  

m = -83/60
