Question

mrs. acosta bought 5 pounds of potatoes at the grocery store today. she also bought 4 pounds of onions and $3\frac{3}{4}$ pounds of carrots. how many pounds of food did mrs. acosta buy in all?
\boxed{\dfrac{\square}{\square}} pounds

Explanation:

Step1: Identify the quantities

Potatoes: 5 pounds, Onions: 4 pounds, Carrots: \( 3\frac{3}{4} \) pounds.

Step2: Convert mixed number to improper fraction

\( 3\frac{3}{4}=\frac{3\times4 + 3}{4}=\frac{15}{4} \)

Step3: Add the quantities

Total = \( 5 + 4+\frac{15}{4} \)
First, \( 5 + 4 = 9 \)
Then, \( 9+\frac{15}{4}=\frac{36}{4}+\frac{15}{4}=\frac{36 + 15}{4}=\frac{51}{4}=12\frac{3}{4} \)

Answer:

\( 12\frac{3}{4} \)
