PIT_PIT [208]

Answer:

$32\ hair\ ties$

Step-by-step explanation:

we know that

To make one hair ties is needed 3 3/8 inches of elastic

using proportion

Find out how many hair ties can you make with 9 feet of elastic

Remember that

$1\ ft=12\ in$

Convert 9 ft to inches

$9\ ft=9*12=108\ in$

Convert mixed number to an improper fraction

$3\frac{3}{8}\ in=\frac{3*8+3}{8}=\frac{27}{8}\ in$

using proportion

$\frac{1}{(27/8)}=\frac{x}{108}\\\\x=108*8/27\\\\x=32\ hair\ ties$
