Question

Kim and her two brothers each use 1 1/2 cups of milk for breakfast. How many fluid ounces of milk do they use in 4 days?

Answer 1

Answer:

They use 144 oz of milk in 4 days.

Step-by-step explanation:

As we know that 1 cup of milk = 8 ounces

$1\frac{1}{2}$ cup of milk = $1\frac{1}{2}$ × 8

                  = $\frac{3}{2}$ × 8

                  =  12 ounces

Kim and her two brothers (3 persons) each use 12 ounces milk for breakfast.

in one day they (3 person) use milk = 12 × 3 = 36 ounces

In 4 days they use milk = 36 × 4 = 144 ounces

They use 144 oz of milk in 4 days.

Answer 2

1 cup = 8 oz.

1 1/2 cup = 12 oz

12oz of milk x 4 days = 48oz in 4 days

make sense?
