In order to solve this, we can just create a simple ratio based on the information that we have. Lets call this unknown value X.
If 1 yard costs $5.00,
then 7/8 yard will cost $x.
Lets cross multiply in order to create equation and solve it for x. So x times 1 equal to 7/8 times 5.
x=7/8 * 5
Multiply the numerator with the number and divide it by the denominator.
x= (7*5)/8
x=35/8
x=$4.375
