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

ElenaW [278]

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

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

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

How to solve <br> -3(4R-8)-36

natima [27]

Answer: -12r-12

Step-by-step explanation: There is no equals sign so you can't solve it but you can simplify it. You start out with -3(4r-8)-36. Then, you use PEMDAS. (-3×4r)+(-3×-8)-36. Then, it turns into -12r×+24-36. You just continue to simplify until you can't anymore. You end up with -12r-12.
