To find the sum of the fractions 2/3 and 7/15, first, we need to make sure the denominators are the same. In this case, they are not the same.
To make the denominators the same, we need to find the least common denominator (LCD). In this case, the LCD is 15 because both 3 and 15 are divisible by 3.
Next, we need to convert both fractions to have a denominator of 15. The first fraction, 2/3, can be converted by multiplying the numerator and denominator by 5: (2/3) * (5/5) = 10/15.
Now that both fractions have the same denominator of 15, we can add them: 10/15 + 7/15 = (10 + 7)/15 = 17/15.
So, the sum of 2/3 and 7/15 is 17/15.
