Question

last week marcy and her roommates ate 3 3/4 cartons of yogurt, and this week they at 5 cartons. how much more yogurt did they eat this week compared to last week? write your answer as a fraction or as a whole or mixed number. cartons

Explanation:

Step1: Convert mixed number to improper fraction

Last week's yogurt: \( 3\frac{3}{4}=\frac{3\times4 + 3}{4}=\frac{15}{4} \)
This week's yogurt: \( 5=\frac{20}{4} \)

Step2: Subtract last week's from this week's

Difference: \( \frac{20}{4}-\frac{15}{4}=\frac{5}{4}=1\frac{1}{4} \)

Answer:

\( 1\frac{1}{4} \)
