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.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
