Answer 2

To add 4 17/45 and 3 13/45, we first need to find a common denominator. The denominator of both fractions is 45, so we don't need to find a new denominator.

We add the whole numbers first:

4 + 3 = 7

Then we add the fractions:

17/45 + 13/45 = (17 + 13)/45 = 30/45

But 30/45 can be simplified by dividing both numerator and denominator by their greatest common factor, which is 15:

30/45 = (215)/(315) = 2/3

So the sum of 4 17/45 and 3 13/45 is:

7 + 2/3 = 7 2/3

Therefore, 4 17/45 + 3 13/45 = 7 2/3.
