Answer 1

Answer:

answer is 1

brcause y= 20

Answer 2

Answer:

$\mathrm{Simplify}\:5\frac{y}{4}-172\frac{y}{5}:\quad -\frac{663y}{20}$

Step-by-step explanation:

$=\frac{5y}{4}-\frac{172y}{5}$

$=\frac{25y}{20}-\frac{688y}{20}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}$

$=\frac{25y-688y}{20}$

$\mathrm{Add\:similar\:elements:}\:25y-688y=-663y$

$=\frac{-663y}{20}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}$

$=-\frac{663y}{20}$
