$if \: \frac{a}{b} = \frac{5}{3} then \: find \: the \: value \: of \: \frac{a + b}{a - b}$
​

Answer 1

Step-by-step explanation:

a+b/a-b = 5+3/5-3

=8/2 = 4.

Answer 2

Answer:

explations answer 4

Step-by-step explanation:

$\frac{a}{b} = \frac{5}{3} \\ \\ = > 3a = 5b \\ \\ = > a = \frac{5}{3} b \\ \\ \frac{a + b}{a - b} = \frac{ \frac{5}{3}b + b }{ \frac{5}{3} b - b} \\ \\ = \frac{ \frac{5b + 3b}{3} }{ \frac{5b - 3b}{3} } \\ \\ = \frac{8b}{2b} = 4$
