My brother is helping me?
OpenStudy (mertsj):
Did you study the other one where I posted the steps and showed you about the common denominator?
OpenStudy (anonymous):
yes I use it for the 7-3/7 problem
OpenStudy (anonymous):
7/1-3/7=49/7-3/7=46/7 as the answer
OpenStudy (mertsj):
This one is the same thing. Use the common denominator 18

What would I do to 9 to change it to 18?
OpenStudy (mertsj):
So if I multiply the denominator by 2, what should I do to the numerator?
