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.
