OpenStudy (mertsj):
Multiply 4 and 11. That answer is equal to the other product that you get when you multiply 8 and m

OpenStudy (linn99123):
so i multiply 8 by each answer choice
OpenStudy (linn99123):
and chich ever one gets to 44 is my answer ??
OpenStudy (anonymous):
44 is not the answer.
OpenStudy (mertsj):
Let's try another approach.
Look at the first fraction.
The top is twice as much as the bottom. Do you see that?
OpenStudy (linn99123):
yes

Make the other fraction like that. Make the top twice as much as the bottom.
OpenStudy (anonymous):
4*11=44 8*m=8m
44=8m
OpenStudy (linn99123):
is ittle be 44/m
OpenStudy (mertsj):
Or in other words, the bottom is 1/2 the top
OpenStudy (anonymous):
Divide both 44 and 8m by 8.
