Connelly has 14 of a cup of water. Ryan has 25 of a cup of water. Grayson has 0.4 less than 2 times Connelly's amount of water. Write the expression that can be used to find how much water Ryan and Grayson have together.
C = 1/4 cup R = 2/5 cup and G has 2(1/4)(6/10) = 12/40 = 3/10 cup
So R and G together have 2/5 + 3/10 = 4/10 + 3/10 = 7/10 cup
This question is very poorly phrased and the meaning is not clear.
