Luna mixes 3/4 cup of orange juce with 1/2 cup of cranberry juice. she gives 5/8 cup of the juice to mags. how much is left in lunas glass? ? peoplee helll nowww

First start with 3/4 + 1/2
Find common denominator which is 4.
Multiply top and bottom of 1/2 by 2.

3/4 + 2/4= 5/4

Now subtract 5/8 from 5/4
Find the common denominator again which is 8
Multiply 5/4 by 2 on both top and bottom
10/8-5/8= 5/8

Answer is 5/8
