Question

For Emma's lemonade recipe, 9 lemons are required to make 18 cups of lemonade. At what rate are lemons being used in lemons per cup of lemonade?

Answer 1

1:2

A rate of 1 lemon per two cups of lemonade

Explanation:

9 lemons for 18 cups can be seen as:

`(9)/(18)`

Simplify by dividing both numbers by 9:

`(9/9)/(18/9) =(1)/(2)`

So, one lemon is used for two cups of lemonade. Half a lemon for 1 cup of lemonade...
