To add these fractions, we need to find a common denominator. The least common multiple of 15 and 3 is 15.
Converting both fractions to have a denominator of 15:
4/15 + 1/3 = (4 * (3/3))/15 + (5 * (1/5))/15
= 12/15 + 5/15
Now that both fractions have the same denominator, we can add the numerators:
= (12 + 5)/15
= 17/15
Therefore, 4/15 + 1/3 = 17/15.
4/15 + 1/3
