Question

Rational number equivalent to -12÷18 whose denominator is -135

Answer 1

Hey,

Sum of two rational numbers which do not have the same denominator, follow the following steps.

1) Obtain the rational nmbers and see whether their denominators are positive or not. If the denominator of one or both of the numbers is negative rewrite the denominators becomes positive.

2) Obtain the denominators of the rational numbers in step 1.

3) Find the LCM of denominators in step 2.

4) Express each one of the rational numbers in step 1 so that the LCM obtained in step 3 becomes their common denominator.

5) Write a rational number whose numerator is equal to the sum of the numerators of rational numbers obtained in step 4 and denominator as the LCM obtained in step 3.

6) The rational number obtained in step 5 is the required sum
