Question

-7/8u = -21 solve for u and simplify your answer as much as possible

Answer 1

Answer: u = 1/24

Explanation:

-7/8u = -21

Multiply both sides by 8u

(8u) -7/8u = -21 (8u)

-7 = -21 (8u)

Divide by -21

-7/-21 = 8u

1/3 = 8u

Divide by 8

(1/3)/8 = u

When dividing fractions, flip and multiply

(1/3) (1/8) = u

u = 1/24

It works if you plug it back in, hope this helps
