13/3+17/5=7 11/15

Explanation:

Let us first add them. As the Least Common Multiple of denominators 3 and 5 is 15, first multiply numerator and denominator of the two fractions to be added so that there denominators become 15 i.e. 13/3 by 5 and 17/5 by 3. Then they can be added easily.

So, 13/3+17/5=(13xx5)/(3xx5)+(17xx3)/(5xx3)=65/15+51/15=116/15

Now as in 116/15 numerator is greater than denominator, therefore we ought to get mixed number by dividing numerator 116 by the denominator 15 and as we get 7 as quotient and 11 as remainder i.e. 116=15xx7+11.

Hence, 116/15=7 11/15
