Question

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes can she make

Answer 1

Petra can make 8 costumes with 12 yards of fabric

Solution:

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires
`1(1)/(2)` yards

To find: number of costume Petra can make

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

`\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}`

Total fabric she has = 12 yards

Fabric needed for 1 costume =
`1(1)/(2) = (2 * 1 + 1)/(2) = (3)/(2)` yards

Therefore,

`\text {number of costume Petra can make }=(12)/(3 / 2)=(12)/(3) * 2=8`

Thus petra can make 8 costumes with 12 yards of fabric
