Question

A 6 inch personal pizza has 610 calories, with 240 of those from fat. A 16 inch pizza is cut into 8 slices. Estimate the number of calories in one slice of a 16 inch pizza.

Answer 1

203 1/3 calories

Explanation:

I make a proportion for inches of pizza to calories

`(6)/(610)` =
`(16)/(x)` I know that a 6 inch pizza has 610 calories, so I am trying to figure out how many calories are in a 16 inch pizza.

I can cross multiply to get

6x = (16)(610)

6x = 9760 Divide both sides by 6

x = 1626
`(2)/(3)` This is how many calories are in a whole pizza. Now I want to know how many calories are in 1 slice. I would take this number and divide by 8.

1626 2/3 as an improper fraction would be

`(4880)/(3)` ÷ 8 Which is the same as

`(4880)/(3)` x
`(1)/(8)` =
`(4880)/(24)`=203
`(1)/(3)`
