y=x/z
6=4/3
18/4
=4.5
when x=4,z=3
y=4/3
y=1.33
In order to calculate correctly, it is important that we are able to understand well the given values. we have
3/4 yard fabric = total amount of available fabric
3/10 yard= amount needed to make one doll
therefore,
number of doll dresses = 3/4 / 3/10 = 5/2 doll dresses
