hope this is helpfulok

Answer 2

Answer: -61/30

Step-by-step explanation:

For these type of questions, ie, addition of rational numbers,

The first step is to find out the LCM of the denominators.

Here the LCM of 5,10&15 is 30.

Now, you have to convert the rational numbers having the denominator as 30 ie, you have to convert them into like fractions.

This can be done by multiplying both the numerator and denominator by a number so that the overall number remains the same and its value does not change.

Here,

-4/5 × 6/6 = -24/30

-7/10× 3/3= -21/30

-8/15 ×2/2 = -16/30

Now, all of them have been converted into like fractions, so you can add the numerators together.

ie, -24/30 + -21/30 + -16/30 = -61/30, which is your answer!

Hope it helps and you're able to solve these kind of questions on your own.....
