add the following
please answer this question please ​

Answer 1

~Question :-

Solve the given fractions :-

$\mapsto \sf{(\frac{-9}{25})+(\frac{-3}{10})}$

~Answer :-

• For finding the sum of the given rational numbers;

$\sf{( \frac{- 9}{25} ) + ( \frac{ - 3}{10} )}$

• Now, make the denominators equal by taking common factors of 25 and 10;

$\leadsto \sf{\frac{ (- 9) + ( - 3)}{50} }$

• Now, we have to solve the integers on the numerator;

$\leadsto \sf{ \frac{ - 12}{50} }$

• Now, reduce the fraction to the lowest term;

$\leadsto \sf{ \frac{ - 12}{50} } \\ \\ \leadsto \sf{ \frac{ \cancel{ - 12}}{ \cancel{50}} } \\ \\ \leadsto \sf{ \frac{ - 6}{25} }$

» Hence, the answer will be $\sf{\frac{-6}{25}}$.

Answer 2

${\large{\sf {\red{ Given :}}}}$

$\frac{ - 9}{25} \: + \frac{ - 3}{10}$

${\large{\sf{\red{Solution :}}}}$

$\frac{ - 9}{25} \: + \frac{ - 3}{10}$

LCM of 25 and 10 = 50

$\frac{ - 9 \times 2}{25 \times 2} \: + \frac{ - 3 \times 5}{10 \times 5}$

=

$\frac{ - 18}{50} \: + \frac{ - 15}{50}$

$\frac{( - 18 )+ ( - 15)}{50}$

=

$\frac{ - 33}{50}$
