Three girls collected geodes in the desert. corinne collected 11 1/8 pounds, ellen collected 4 5/8 pounds, leona collected 3 3/4 pounds. how much more did corinne collect than the other two girls combined

The correct answer is:  2 3/4

Step-by-step explanation:

11 1/8 - (4 5/8 + 3 3/4)

First we need to expand the third fraction with the number two and get:

11 1/8 - (4 5/8 + 3 6/8) = 11 1/8 - 7 11/8 = 11 1/8 - 8 3/8

Now we need to convert an entire number at the first fraction in 8/8

10 9/8 - 8 3/8 = 2 6/8 = 2 3/4

God with you!!!
