Louisa has 4 yards of fabric. She uses 25 yard of fabric to make a doll dress. How many doll dresses can Louisa make with the fabric? Choose the number line model that shows the answer.

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Step-by-step explanation:

This are the options:

A. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 4 equal parts.

B. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 8 parts.

C. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 5 equal parts.

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.

Amount of Fabric owned by Louisa = 4 yards

If she uses 2/5 yards to make a doll dress, to get the number of dolls that 4 yards can make we will say:

1 doll = 2/5 fabric

x doll = 4 fabrics

Cross multiply

2/5 * x = 4*1

2x/5 = 4

cross multiply

2x = 20

Divide both sides by 2:

2x/2 = 20/2

x = 10

This means that she can make 10 dolls using 4 yards of fabric.

Hence the correct option will be

D. Number line from 0 to 4 is divided into 20 equal parts. Number line is grouped into 10 equal parts.
