QUESTION :- Subtract $\frac{-3}{4}$ from $\frac{-9}{10}$.

ANSWER :-

ATQ → We have to subtract $\frac{-3}{4}$ from $\frac{-9}{10}$.

$\frac{ - 9}{10} - ( \frac{ - 3}{4} )$

$= \frac{ -9 }{10} + \frac{3}{4}$

Now we have to make the denominators equal.

LCM of 4 and 10 is 40.

$= \frac{ - 9}{10} \times \frac{4}{4} + \frac{3}{4} \times \frac{10}{10}$

$= \frac{ - 36}{40} + \frac{30}{40}$

$= \frac{ - 6}{40}$

Upon cancelation of the term that is left now,

We get,

$= \frac{ - 3}{20}$

Hence the answer of the given question is $\frac{-3}{20}$.
