here it is ⤵️

Step-by-step explanation:

When adding or subtracting rational numbers,follow the rules on adding or subtracting integers. That is, add the numbers when they have same signs and copy the common sign, or subtract the numbers when they have different signs and then copy the sign of the number with the bigger absolute value.

Hope it helps u

Rational numbers are integer fractions.

Now if the denominator is the same adding or subtracting fractions is the same as adding or subtracting their numerators:

ac±bc=a±bc

Now if the denominators differ you can find a common denominator (usually the least) and use this trick:

ab±cd=a⋆±c⋆lcm(b,d)

Note

a⋆=a×lcm(b,d)b

and

c⋆=c×lcm(b,d)d

Integers are these rational numbers where in the most simplified version of the integer fraction the denominator is 1.
