Use multiplying by one to find an expression equivalent to 12/11 with a denominator of 77z.

I have an entire worksheet of problems like this. Could someone please explain to me how to complete this type of problem.

Look at the first fraction 12/11

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

Equivalent fraction of 12/11 = 84/77

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

Hope this helps.
