The question:

1/3 + 5/15


The answer:


1/3 + 5/15

To add these fractions, they must have a common denominator

Factor the second fraction

1/3 + (5)/(3*5)

Cancel the factors in the numerator and denominator which are equal

1/3 + (5/5)*(1/3)

1/3 + 1*(1/3)

1/3 + (1/3)

1/3 + 1/3

Both fractions can now be added because they each have the same denominator

(1+1)/3

(2)/3

2/3


The final answer is: 2/3





Thanks for writing.
