Hi,

Given $$\frac{b}{a+b} = \frac{7}{12}$$

or $$\frac{a+b}{b} = \frac{12}{7}$$

=> $$\frac{a}{b} + 1 = \frac{7}{12}$$
=> $$\frac{a}{b} = \frac{5}{7}$$ Answer: B.

Please modify the denominator of the question. It should be b/(a+b) = 7/12.

b/a + b and b/(a + b) is not the same. Please modify the question.

Cheers.

Hi,

A Quite easy question,b/(a + b) = 7/12

Here b=7 And a+b=12 then a=5 hence a/b=5/7

Let’s cross-multiply the given equation:

b/(a + b) = 7/12

12b = 7a + 7b

5b = 7a

5/7 = a/b

Answer: B
