Solve this question and how to do it

Answer 1

Explanation:

7/15 + 3/5

I'd multiply 3/5 by 3 so that both of the denominators (bottom number) are the same.

Now all we have to do is add the Numerators tog

7/15 + 9/15ether (the top number)

7/15 +9/15 = 16/15 or 1 1/15

Answer 2

Explanation:

As the fractions are not like fraction, find LCM for 5 and 15

5 is a prime number and 15 is multiple of 5.So, LCM = 15

`(3)/(5)=(3*3)/(5*3)=(9)/(15)\\\\(7)/(15)+(3)/(5)=(7)/(15)+(9)/(15)`

`= (7+9)/(15)\\\\=(16)/(15)\\\\= 1(1)/(15)`
