2/5 + 3/15
= 2/5 + (3 ÷ 3)/(15 ÷ 3)
= 2/5 + 1/5
= (2 + 1)/5
= 3/5
Your answer is correct.
= 2/5 + (3 ÷ 3)/(15 ÷ 3)
= 2/5 + 1/5
= (2 + 1)/5
= 3/5
Your answer is correct.

GIVEN
2/5 + 3/15
Getting the least common denominator of the above and simplifying,
6/15 + 3/15 = 9/15
and reducing the above (dividing both numerator and denominator by 3), then
9/15 = 3/5
So, YES ... you are correct.

Before you can add fractions together, they need a common denominator.
2/5 + 3/15 = 2/5 + 1/5
= 3/5
Yep, you got it. :)
