Question

If a +b/a −b=5/3, what are the following ratios? a −b/3bIf a +ba −b=53, what are the following ratios?a −b3b

Answer 1

Answer:

1

Step-by-step explanation:

$\frac{a+b}{a-b}$ = $\frac{5}{3}$

⇒ 3(a+b) = 5(a-b)   (Cross-multiplying)

⇒ 3a + 3b = 5a - 5b

⇒ 8b = 2a

⇒ a = 4b

∴ $\frac{a-b}{3b}$ = $\frac{4b - b}{3b}$ = $\frac{3b}{3b} = 1$
