Michelle was told to drink 2 1/2 cups of orange juice today. michelle drank 7/8 of a cup in the morning, 3/8 of a cup at lunch, and 5/8 of a cup at dinner. how many cups of of orange juice did michelle drink today? a.1 1/2 b.1 5/8 c.1 7/8 d.2 1/2

The answer is C, 1 7/8. 
First, you add 7/8, 3/8, and 5/8 to get 15/8.
Next, simplify 15/8 by finding how many times 8 goes into 15, which is 1 time because 8 x 2 is 16. 
Third, you subtract 8 from 15 because 8 goes into 15 one time. This gives you 7. 
Therefore, the answer is 1 7/8.
I hope I helped!
