Melinda drew a model to determine how many fourths are in 3 wholes. Three circles are shown. Each circle is divided into 4 fourths. Which of the following division problems describes Melinda's work? A. 4÷3=43 B. 3÷14=12 C. 4÷13=12 D. 3÷4=34

B. 3 ÷ 1/4 = 12  

This is the correct division problem because the result is 12 and we're calculating how many fourths are in 3 wholes.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of circles = 3  

Number of divisions of every circle = 4  

2. Which of the following division problems describes Melinda's work?

A. 4 ÷ 3 = 4/3  

It's incorrect because the total number of fourths in 3 circles is 12.  

B. 3 ÷ 1/4 = 12  

This is the correct division problem because the result is 12 and we're calculating how many fourths are in 3 wholes.

C. 4 ÷ 1/3 = 12  

It's incorrect because the question is to determine how many fourths are in 3 wholes, not how many thirds are in 4 wholes.  

D. 3 ÷ 4 = 3/4  

It's incorrect because the total number of fourths in 3 circles is 12.
