What is the length of cloth needed to make 24 shirts if each shirt is made from .75 yards of material?
RideAnS [48]

Answer:

18 yards of material needed to make 24 shirts

Step-by-step explanation:

The unit rate is

        1 shirt

------------------------------ = 1 1/3 shirts per yard of material = 4/3 shirt/yard

 0.75 yards material

This rate could also be written as 3/4 yard per shirt

Multiply this latter rate by 24 shirts:

 3 yard

-------------- * 24 shirts = 18 yards of material needed to make 24 shirts

 4 shirt
