What is 1 and 2/15 + 4/3 =

1 2/15 + 1 5/15 = 2 7/15

I think it would be 2 and 7/15

To find the sum of 1 and 2/15 + 4/3, we need to first convert the mixed number 1 and 2/15 into an improper fraction.

To do this, we multiply the whole number, 1, by the denominator of the fraction (15) and add the numerator (2). This gives us (1 * 15) + 2 = 15 + 2 = 17.

So, 1 and 2/15 can be written as the improper fraction 17/15.

Now we can add the fractions together.

To add fractions with different denominators, we need to find a common denominator. In this case, the least common multiple (LCM) of 15 and 3 is 15.

We need to make both fractions have the denominator of 15.

For 17/15, we can keep the denominator as it is since it's already 15.

For 4/3, we multiply both the numerator and denominator by 5 to get a denominator of 15. This gives us (4 * 5) / (3 * 5) = 20/15.

Now, we can add the fractions together:

17/15 + 20/15 = (17 + 20) / 15 = 37/15.

Therefore, the sum of 1 and 2/15 + 4/3 is 37/15.
