Convert these unlike fractions to equivalent like fractions and add them. You must use the LCD to get the answer correct. If possible, reduce the final sum (PLEASE answer all 3 boxes)

3/15, 10/15, 13/15

Step-by-step explanation:

We want 1/5 and 2/3 to share a common denominator.

1/5 has a denominator of 5, and 2/3 has a denominator of 3. They are both prime, so you can't have a smaller LCD than they multiplied, which is 15.

To make 1/5 into a denominator of 15, we multiply both the numerator and denominator by 3 (15 divided by 3) to make sure the fraction stays the same.

We get (1×3)/(5×3)=3/15

Apply this to 2/3, but instead of multiplying by 3, which gives you a denominator of nine, we multiply by 5 to make sure we get 15.

We get (2×5)/(3×5)=10/15

Now we see 3/15+10/15, using (numerator+numerator)/(denominator+denominator).

We get 13/15
