Ruby's water bottle holds 1 9/10 liters of water. Noland's water bottle holds 2 3/5 liters of water. Noland says that his bottle holds about 1/2 liter more water than Ruby's. Round to the nearest fourth, 1 9/10 is closest to ------- and 2 3/5 is closest to -------- . The difference between the bench mark is --------- , so Nolan's estimate is ----------.
Step-by-step explanation: the first fraction is equal to 1 36/40, so it is closer to 1 40/40 than 1 30/40. The second fraction is equal to 2 12/20, so it is closer to 2 10/20 than 2 15/20.
