Answer 2

Given :-

• It is given to solve;

$\sf \frac{3}{10} + \frac{-7}{10}$

Answer :-

Here we can use the following identical values for the solution;

$\sf{ \frac{3}{10} + \frac{ - 7}{10} }$

$\leadsto \sf{ \frac{ 3 + ( - 7)}{10} }$

$\leadsto \sf{ \frac{ - 4}{10} }$

$\leadsto \sf{ \frac{ \cancel{ - 4}}{ \cancel{10}} }$

$\leadsto \bf \red{ \frac{ - 2}{5} }$

$\mapsto$ Hence, the solution for the rational numbers will be $\sf \frac{-2}{5}$.

★ More Information :-

• For solving rational numbers or integers we should always remember that;

(Positive) × (Positive) = (Positive)

(Negative) × (Negative) = (Positive)

(Positive) × (Negative) = (Negative)

(Negative) × (Positive) = (Negative)
