Question

How many band uniforms can be made with 131 3/4 yards of fabric if each uniform requires 3 7/8 yards

Answer 1

The question can be read as how many $3 \frac{7}{8}$ can be made out of $131 \frac{3}{4}$

$131 \frac{3}{4}$÷$3 \frac{7}{8}$ ⇒ We need to change each mixed number into an improper fraction

$131 \frac{3}{4}= \frac{[131*4]+3}{4}= \frac{527}{4}$
$3 \frac{7}{8}= \frac{[3*8]+7}{8} = \frac{31}{8}$

$\frac{527}{4}$÷$\frac{31}{8}$
$\frac{527}{4}$×$\frac{8}{31}$
$\frac{527*8}{4*31}= \frac{4216}{248} =17$

Answer: 17 uniform
