Question

What is -7/12 + 3/8?

Answer 1

`(-5)/(24)`

Explanation:

let's use a common denominator! the easiest way is to multiply each side's numerator and denominator by the other's denominator. let's do this problem!

`(-7(8))/(12(8))` ---->
`(-56)/(96)`

`(3(12))/(8(12))`----->
`(36)/(96)`

now that we have similar denominators, we can add the two numerators together!

-56 + 36 = -20!

`(-20)/(96)`

but wait! we can simplify it by dividing by 5 on both the numerator and denominator,

`(-5)/(24)`
