Question

Question: A jug holds 1 1/4 liters of water. Ben pours 3/5 of a liter into a glass. How many liters of water are still in the jug? Select the model that represents this amount.

Answer 1

C.

Explanation:

To answer this, we first have to make common denominators. to do this, we do (5/4) x 5 and (3/5) x 4, to get new fractions, 25/20, and 12/20. then, we can subtract 25/20 and 12/20 easily to get the remaining liters, 13/20. Then, to pick the right model, we need to find which box(es) has 20 squares in it, which are Boxes A and C. Now, we can just count which one contains 13 filled-in squares, which is Box C. So that is our answer, C.
