### Question #14

Friday, November 27, 2009
Hey 9-05! Today I'll be showing you how to answer question #14.

First of all you need to read the information given to you and pick out key words:

Li and Ray shared a vegetarian pizza and a Hawaiian pizza of the same size. The vegetarian pizza was cut into eight equal slices. The Hawaiian pizza was cut into six equal slices. Li ate two slices of the vegetarian pizza and one slice of the Hawaiian pizza. Ray ate two slices of the Hawaiian pizza and one slice of the vegetarian pizza.

a) Who ate more pizza?
-To find out who ate more pizza you need to add the sized pieces they ate together
-Li ate two slices of the vegetarian pizza (out of 8) and one slice of the Hawaiian pizza (out of 6)
-2/8 + 1/6=

-When adding fractions you must have a common denominator
-Add the numerators, leave the denominator as it is
-Simplify if possible

-This means Li ate 10/24 of the pizzas

-Ray ate two slices of the Hawaiian pizza (out of 6) and one slice of the vegetarian pizza (out of 8) -2/6 + 1/8=

-When adding fractions you must have a common denominator
-Add the numerators, leave the denominator as it is
-Simplify if possible
-This means Ray ate 11/24 of the pizzas

11/24 is larger than 10/24 so that means Ray ate more pizza.

b) How much more did that person eat?

-Since there are already common denominators,
all you need to do is subtract the numerators

Ray ate 1/24 more pizza than Li.

c) How much pizza was left over?

-There was a total of 2 pizzas (2/1)
-Li ate (10/24) of the pizzas
-Ray ate (11/24) of the pizzas
-The answer is how much pizza was left after they ate

There was 1 1/8 pizza left over.

Woot! That's it! Please COMMENT if I made any mistakes, you don't understand something, or if you just feel like commenting. ^__^

Hi Joseph! This is a really nice post! But there are some mistakes. They're really minor, though. The ones I noticed were on b) you had capitalized "much" when it wasn't supposed to be, and on the second picture you didn't leave a space before a bracket. You could also capitalize those side notes on the other pictures because you did so on the last picture. I think that's about it. Great job!
