Question

Deirdre served each of her classmates a hamburger weighing 2/3 pound. If she bought 8 pounds of hamburger meat, how many hamburgers did she serve? *

Answer 1

She served 12 hamburgers.

Explanation:

This question is solved by proportions, using a rule of three.

Each hamburger weighs 2/3 of a pound. She bought 8 pounts. How many hamburgers is this?

2/3 pound - 1 hamburger

8 pounds - x hamburgers

Applying cross multiplication:

`(2x)/(3) = 8`

`x = (8*3)/(2)`

`x = (24)/(2)`

`x = 12`

She served 12 hamburgers.
