Answer 1

18/5-16/3=54/15-80/15=-26/15 = -1 11/15

Answer 2

Sure, I can help you with that. To add mixed numbers, you need to convert them to improper fractions and then perform the addition.

Let's convert the mixed numbers to improper fractions first:

3 3/5 = (5 * 3 + 3) / 5 = 18/5 -5 1/3 = (3 * -5 + 1) / 3 = -14/3

Now we can add the fractions:

18/5 + (-14/3)

To add fractions, we need a common denominator. In this case, the common denominator is 5 * 3 = 15.

Now we can rewrite the fractions with the common denominator:

(18/5) * (3/3) + (-14/3) * (5/5) = 54/15 + (-70/15)

Finally, we can add the fractions:

54/15 + (-70/15) = (54 - 70) / 15 = -16/15

Therefore, 3 3/5 + (-5 1/3) = -16/15.
