Question

Simplify each expression. Show work and explain.
24. 3 over 5d / (-9) over (15df)
25. p^3 over 2q / (-p) over 4q
26. 2x^3y over z^5 / (4xy over z^3)^2
27. xy over a^3 / (xy over ab)^3

Answer 1

\[\Large \frac{3}{5d} \div \frac{-9}{15df}\]

is the same as

\[\Large \frac{3}{5d} \times \frac{15df}{-9}\]

Answer 2

from there you multiply straight across and you simplify as much as possible

Answer 3

@phi

Answer 4

correct

Answer 5

yes

Answer 6

What about #25

Answer 7

use the same idea: flip the second fraction and multiply

then reduce as much as possible

Answer 8

I did and I am stuck. I have so far 4p^3q over (-2pq)

Answer 9

p^3 divided by p = ???

Answer 10

oh before that 4 divided by -2 = ???

Answer 11

and finally q/q =??
