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.
