Question

ADD THE RATIONAL NUMBERS -7/13 AND 6/5

Answer 1

We are given the following rational numbers to add

`-(7)/(13)+(6)/(5)`

Step 1:

We need to make the denominator the same

The LCM of 13 and 5 is 65

`-(7)/(13)+(6)/(5)=(-5\cdot7)/(65)+(13\cdot6)/(65)=(-35)/(65)+(78)/(65)`

Step 2:

Since the denominators are the same, simply add the numerators

`(-35)/(65)+(78)/(65)=(-35+78)/(65)`

Step 3:

Simplify to the lowest terms

`(-35+78)/(65)=(43)/(65)`

Therefore, the simplified answer is 43/65
