Question

if a upon b=7upon3 then find the value of a-b upon b
​

Answer 1

Answer:

$\frac{4}{3}$

Step-by-step explanation:

Given :

$\frac{a}{b} = \frac{7}{3}$

Procedure :

Subtracting 1 from both sides :

$\frac{a}{b} - 1 = \frac{7}{ 3} - 1$

LCM on the Left Hand Side of the Equation is b.

LCM on the Right Hand Side of the Equation is 3.

=> $\frac{a}{b} - \frac{b}{b} = \frac{7}{3} - \frac{3}{3}$

=> $\frac{a - b}{b} = \frac{7 - 3}{3}$

=> $\frac{a - b}{b} = \frac{4}{3}$

Hence the answer is 4/3.
