Question

Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to Mags. How much is left in Luna’s glass?

Answer 1

To add fractions, you have to have like denominators.

2 of your fractions have like denominators so you don't have to touch them. With 3/4, you have to find what number times 4 equals 8.

That number is two, what ever you do to the bottom you have to do to the top. So 3 * 2 is 6 and 4 * 2 is 8.

Your new fraction is now 6/8.

Regularly add your fractions together 6/8+3/8. That gets you 9/8

Then subtract the amount that you gave away. That would be 9/8 - 5/8 = 4/8

4/8 simplified is 1/2.

Now Luna only has 1/2 of a glass of juice

Answer 2

4/8 of the juice is left in Luna's glass, 3/4 = 6/8. 3/8+6/8= 9/8. 9/8-5/8=4/8
