Answer 2

QUESTION :- $\frac{2}{5} + \frac{9}{7} -\frac{1}{6}$.

ANSWER :-

$\frac{2}{5} + \frac{9}{7} -\frac{1}{6}$

The denominator are not equal so first we have to make them equal.

LCM of 5, 7 and 6 is 210.

$= \frac{2}{5} \times \frac{42}{42} + \frac{9}{7} \times \frac{30}{30} - \frac{1}{6} \times \frac{35}{35}$

$= \frac{84}{210} + \frac{270}{210} - \frac{35}{210}$

We have to solve this question using BODMAS Rule; first add then subtract.

$= \frac{319}{210}$

Hence the answer of the question is $\frac{319}{210}$(Improper fraction).
