Question

Alicia buys a 5 pound bag of rocks for a fish tank. She uses 1 1/8 pounds of small fish bowl. How much is left?

Answer 1

I believe that there is 3 7/8 pounds of rocks left since 5lbs - 1 1/8lbs = 3 7/8lbs and 3 7/8lbs + 1 1/8lbs = 5lbs. Hope this helps and have a nice day!

5-1-1/8=
4+1-1-1/8=
4-1+8/8-1/8=
