Question

-7/8+3/4
answers plus steps

Answer 1

`\large\boxed{-(7)/(8)+(3)/(4)=-(1)/(8)}`

Explanation:

To add two fractions we must have a common denominator.

`8=4\cdot2`

Therefore

`LCD=8`

`-(7)/(8)+(3)/(4)=-(7)/(8)+(3\cdot2)/(4\cdot2)=-(7)/(8)+(6)/(8)=(6)/(8)+\left(-(7)/(8)\right)=(6)/(8)-(7)/(8)\\\\=(6-7)/(8)=(-1)/(8)=-(1)/(8)`
