Answer 2

Answer:

The sum of $\frac{5}{7}+(-\frac{4}{5})$ will be $-\frac{3}{35}$

Step-by-step explanation:

As per data given in the question,

We have,

$\frac{5}{7}+(-\frac{4}{5})$

To find the sum of given rational numbers, we must first equalize their denominators by taking the LCM if they are not equal.

So, the LCM of $7$ and $5$ is $35$.

Convert $\frac{5}{7}$ and $\frac{4}{5}$ to fractions with denominator $35$,

$=> \frac{25}{35} -\frac{28}{35}$

Now, both denominators are the same,

Therefore we take denominator as common and subtract the numerators,

$=> \frac{25-28}{35}$

$=> -\frac{3}{35}$

Hence, the required solution is $-\frac{3}{35}$
