IF KELLY GAVE 1/3 OF THE PIZZA TO HOLLY AND 1/5 TO DIANE HOW MUCH DID SHE HAVE LEFT.
I think it might be 8/15. I am not a tutor, but that is what I think, just so you know.
Hilary is right.
5/15 + 3/15 = 8/15
1- 1/3- 1/5=
15/15- 5/15- 3/15=
7/15 of the pizza is left
Kayla is correct. Hilary and I forgot to subtract.
She has 7/15 left.
To find out how much pizza Kelly had left after giving portions to Holly and Diane, we need to subtract the fractions of the pizza she gave away from the whole pizza.
First, let's calculate the fraction of the pizza Kelly gave to Holly. Kelly gave away 1/3 of the pizza to Holly.
To subtract fractions, we need a common denominator. The least common multiple (LCM) of 3 and 5 is 15. Therefore, we need to rewrite the fractions with a denominator of 15.
1/3 can be written as (1/3) * (5/5) = 5/15
1/5 can be written as (1/5) * (3/3) = 3/15
Now, let's subtract these fractions to find out how much pizza Kelly had left:
1 - (5/15) - (3/15) = (15/15) - (5/15) - (3/15) = 7/15
Therefore, Kelly had 7/15 of the pizza left after giving portions to Holly and Diane.
