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

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

$T=8\frac{1}{2}\ yards\\\\ x= 2\frac{1}{2}\ yards\\ \\y=3\ yards$

substitute in the formula above

$R=8\frac{1}{2}-(2\frac{1}{2}+3)$

$R=8\frac{1}{2}-(5\frac{1}{2})$

$R=3\ yards$

therefore

the answer is

the remaining of fabric is $3\ yards$

Answer 2

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