a rectangular family room has 204 square feet of it takes 1 3/8 yards of material to make one shirt. how many shirts can be made from 16 1/2 yards of material?
1.1
2.3
3.6
4.12
5.24
What does the family room have to do with this problem?
For the shirt problem -- divide 16.5 yards by 1.375 yards.
To find out how many shirts can be made from 16 1/2 yards of material, you need to divide the total length of material by the amount of material required to make one shirt.
Given that it takes 1 3/8 yards of material to make one shirt, we'll convert 16 1/2 yards to an improper fraction:
16 1/2 yards = 16 + 1/2 yards = (16 * 2 + 1) / 2 = 33/2 yards
Now, divide the total length of material (33/2 yards) by the amount of material required to make one shirt (1 3/8 yards):
(33/2 yards) ÷ (1 3/8 yards) = (33/2 yards) ÷ (11/8 yards)
When dividing by a fraction, you can multiply by its reciprocal:
(33/2 yards) × (8/11 yards) = (33 * 8)/(2 * 11) = 264/22 = 12 shirts
Therefore, you can make 12 shirts from 16 1/2 yards of material.
So the correct answer is 4.12.
