Elena drank 3 liters of water yesterday. Jada drank 3/4times as much water as Elena. Lin drank twice as much water as Jada. Explain how you know if Jada drank more or less than Elena.

Answer 1

E=3

J = 3/4 x 3 = 9/4 = 2 1/4

L = 2J = 2(9/4) = 9/2 = 4 1/2

4 1/2 > 3

L > E

Lina drank more than Elena

2 1/4 < 3

Jada drank less than Elena

J<E<L

2 1/4 < 3 < 4 1/2

2.25 < 3.00 < 4.50
