-3%2F5%2B8%2F35 Start with the given expression




In order to add these two fractions, these fractions need to have a common denominator.


In order to do that, we simply find that the LCM of 5 and 35 is 35 (note: if you need help with finding the LCM, check out this solver)


Now we need to get each denominator to 35



%287%2F7%29%28-3%2F5%29%2B8%2F35 Multiply -3%2F5 by %287%2F7%29


-21%2F35%2B8%2F35 Multiply -3%2F5 and %287%2F7%29 to get -21%2F35



Since both fractions have a common denominator of 35, we can now combine the fractions


%28-21%2B8%29%2F35 Combine the fractions


-13%2F35 Add the numerators



So

-3%2F5%2B8%2F35=-13%2F35




So you are correct. To verify your answer, simply evaluate these fractions using a calculator.
