he had 1/3 of her pizza left

Wrong, Ravneet!

To find out how much pizza Kelly had left after giving 1/3 to Holly and 1/5 to Diane, we need to subtract the portions given away from the whole pizza.

1/3 represents the portion given to Holly, and 1/5 represents the portion given to Diane. So, to calculate the amount given away, we need to find the sum of 1/3 and 1/5:

1/3 + 1/5 = (5/15) + (3/15) = 8/15

Thus, Kelly gave away 8/15 of the pizza.

To find out how much pizza Kelly had left, we need to subtract 8/15 from 1 (since the whole pizza represents 1):

1 - 8/15 = 15/15 - 8/15 = 7/15

Therefore, Kelly had 7/15 of the pizza left.
