Question

I’m trying to find the missing fraction for this 1/3 + blank =7/12

Answer 1

1/4

Explanation:

The LCD here is 12. Subtract 1/3, or 4/12, from 7/12, to obtain the missing fraction. 7/12 - 4/12 = 3/12, or 1/4. The missing fraction is 1/4.

Answer 2

`(1)/(3)+x=(1)/(12)\\\\(4)/(12)+x=(1)/(12)\\\\x=-(3)/(12)=-(1)/(4)`
