Hello there! :)

Answer:

1.
\boxed{(13)/(15) }

2.
\boxed{(7)/(12) }

Explanation:

1. 3/5+4/15

First, you multiply by numerator and denominator.

3*3=9

5*3=15


=(9)/(15)

Then, you had to combine by the fractions.


(9)/(15)+(4)/(15)

Add by the numbers from left to right.

9+4=13

13/15 is the final answer.

2. 5/6-1/4

First, you multiply by 2 both sides of numerator and denominator.

5*2=10

6*2=12

10/12

3/12


(10)/(12)-(3)/(12)

Subtract by the numerator.

10-3=7

7/12 is the final answer.

Hope this helps!

Thanks!

Have a nice day! :)
