Question

For every 2 text message Ms. Harris sends, Mr. Rosenbaum sends 5. How many messages would Ms. Harris send if Mr. Rosenbaum sends 40 messages?

Answer 1

16

Explanation:

Set up a ratio where `X` is the number of texts Ms Harris makes when Mr Robinson sends 40.

`2/5 = X/40`

`(5*2)/5 = (5*X)/40`

`2 = (5X)/40`

`2* 40 = 40*(5X)/40`

`80 = 5X`

`80/5 = (5X)/5`

`16 = X`
