Question

Each day, Tally's baby sister eats 1/4 cup of rice cereal in the morning and 1/4 cup rice cereal in the afternoon.

It will take Tally's sister A. 2 days to eat 2 cups of rice cereal.
B. 3
C. 4

Answer 1

Each day she eats 1/2 cups of rice. But we want to know how long it will take to each 2 cups worth. so lets make an equation.

.5x = 2
Divide both sides by .5

x = 4

So it will take 4 days to eat 2 cups of rice cereal.
