DragonSlayer554 can you figure this one out?

Do you mean?         You really need to learn to use brackets properly!!!!!

$$\frac{7}{8}\times \frac{a}{-3/4}\\\\
=\frac{7}{8}\times a\times \frac{-4}{3}\\\\
=\frac{7}{2}\times a\times \frac{-1}{3}\\\\
=\frac{-7a}{6}$$

I will do one part at a time, ok?

First part.

a7⁄8*a

((a*a7)/8)

Second part

The second part doesn't come up on the calculator. Why?

second part

⁄ ‾³⁄4

answer (I think): -(((a*a7)/96))

hope it helps
