4/15 + 3/5 = 4/15 + 3 x 3/5 x 3 = 4/15 + 9/15 = 13/15

Answer: 2 and 3/5

Step-by-step explanation: To add these two fractions together, we start by finding their common denominator.

The common denominator for 15 and 5 is 15.

If you need a review on how to find the lowest common denominator, ask me in the comments below and I would be happy to explain.

Notice that 4/15 already has 15 in the denominator so it stays the same.

However, we multiply top and bottom of our

second fraction by 3 to get 9/15.

Now we have 4/15 + 9/15 which simplifies to 13/15.
