Each system is independent of one another, so you multiply the probabilities of failure for each

P(A and B) = P(A)*P(B)
P(A and B) = 0.01*0.03
P(A and B) = 0.0003

2x/7 divides by 4y/14?

Sonbull [250]

Remember that $\frac{\frac{a}{b}}{\frac{c}{d}}=(\frac{a}{b})(\frac{d}{c})=\frac{ad}{bc}$

try and simpliy each first
4y/14=(2/2)(2y/7)=2y/7

so 2x/7 divided by 2y/7
$\frac{\frac{2x}{7}}{\frac{2y}{7}}=(\frac{2x}{7})(\frac{7}{2y})=\frac{(2x)(7)}{(2y)(7)}$ = $\frac{14x}{14y}=\frac{x}{y}$
