Alisa is making bracelets with leather bands. each bracelet uses 7 3/4 inches of leather banding. she plans to make 4 bracelets.

Artyom0805 [142]

Each bracelet is $7 \frac{3}{4} inches$

Turn it into an improper fraction

Multiply 7 and 4 and add 3 which is over 4 which is $\frac{31}{4}$

Multiply by 4 | for each bracelet being made

$\frac{31}{4} * \frac{4}{1}$ $= \frac{124}{4}$

124÷4=31
