Ella is making 3 batches of banana milkshake she needs 3/4 gallon of milk for each bath. her measuring cup holds 1/4 gallon. how many times will she needs to fill the measuring cup to make all 3 bathes of milkshake.

1 batch need 3/4 gallon of milk

She has 1/4 gallon cup

(3/4) divided by (1/4)

A technique in math is just flip the divider which is (1/4) to (4/1)
so it becomes (3/4) multiply (4/1) = (3x4) / (4x1) = 12/4 = 3 times for one batch

She needs three batches so 3 x 3 = 9 times to fill the measuring cup to make all 3 batches of milkshake.
