Question

Casey has 8 1 2 yards of fabric. She uses 2 1 2 yards to make pillows and 3 yards to make curtains. How much fabric is remaining

Answer 1

the answer is 3 if the fratcion was 8 1/2

Answer 2

Let

x-------> yards of fabric used to make pillows

y-------> yards of fabric used to make curtains

T------> total yards of fabric

R-------> remaining yards of fabric

we know that

`R=T-(x+y)`

we have

`T=8(1)/(2)\ yards\\\\ x= 2(1)/(2)\ yards\\ \\y=3\ yards`

substitute in the formula above

`R=8(1)/(2)-(2(1)/(2)+3)`

`R=8(1)/(2)-(5(1)/(2))`

`R=3\ yards`

therefore

the answer is

the remaining of fabric is
`3\ yards`
