3
as a rational number with:
a) numerator = -28
Addition
en adding two or more rational numbers, f
en, add the numerators.​

Answer 1

Answer:

We will learn the addition of rational number with same denominator. In order to add two rational numbers having the same denominator, we follow the following steps:

Step I: Let us obtain the numerators of two given rational numbers and their common denominator.

Step II: Add the numerator of two given rational numbers obtained in step I.

Step III: Write a rational number whose numerator is the sum of two given rational numbers obtained in step II and retain the common denominator (simplify if required).

From the above follows steps we conclude that if ab and cb are two rational numbers with the same denominator, then ab + cb = a+cb.

Answer 2

Step-by-step explanation:

3*-7/1*-7= -28/-7
