Is the denominator 77z or 77?

Find the denominator which is 11
Find denominator of second fraction which is 77

What do you multiply 11 by to get 77?

You multiply 11 by 7 to get 77

Whatever you do to the denominator you do do the numerator.

So 12*7 = 84

To check your answer divide 12 by 11 and 84 by 77, you should get the same answer.

Hope this helps.
