Answer 2

$\frac{47}{126}$ or 0.37

Subtracting $\frac{334}{36}$-$\frac{187}{21}$,

By taking LCM for denominators,

36,21

LCM is 252

Multiplying the first numerator with 7

Multiplying the second numerator with 12

$\frac{(334*7)-(187*12)}{252}$

=$\frac{2338-(187*12)}{252}$

=$\frac{2338-2244}{252}$

=$\frac{94}{252}$

=$\frac{47}{126}$

=0.37

By another method without taking LCM,

Multiplying the first numerator with 21 and the second numerator with 36

Multiplying both the denominator

=$\frac{(334*21)-(187*36)}{36*21}$

=$\frac{(7014)-(187*36)}{36*21}$

=$\frac{(7014)-(6732}{36*21}$

=$\frac{(7014)-(6732)}{756}$

=$\frac{282}{756}$

=$\frac{141}{378}$

=$\frac{47}{126}$

=0.37
