Question

add the following rational numbers
2whole 5/7 and -13/-14​

Answer 1

Answer:

51/14

Step-by-step explanation:

In -13/-14 cancel - sign with another - sign & it will become 13/14

Now to add all we have to make the denominator (the lower figure after / sign) same

So multiply and divide 2 by 14 = 2x14 =28/14

Multiply 5/7 by 2 = 5x2=10/7x2=10/14

Now all three have 14 as denominators

We can now add numerators = 13+28+10=51

The answer is 51/14
