Respuesta :
I believe she messed up in Step 2, it wouldnt be 7/8 it would be 6/8
Answer : She made a mistake in Step two
She should have put :
3/4 + 5/8 = 6/8 + 5/8
Because If you want to make 3/4 have 8 as a common denominator, you have to multiple the top and bottom by 2. and 3*2 = 6, the girl put 7
