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.
