Question

What is the unit price for 3 1/4 yards for $13?

Answer 1

Greetings!

$3 \frac{1}{4} /3\frac{1}{4}=1$
Therfore to find the cost for unit, we must divide the cost by:
$3 \frac{1}{4}$ 

$=13/3\frac{1}{4}$
Simplify.
$=\frac{13}{1} /3\frac{1}{4}$
Convert mixed number into improper fraction.
$=\frac{13}{1} /\frac{13}{4}$
Simplify.
$=\frac{13}{1}*\frac{4}{13}$
$=\frac{52}{13}$
Convert back to mixed number.
$=4$

The unit cost for a yard is $4.

Hope this helps.
