Question

Landon can text 100 words in 20 minutes. At this rate, how many words could he text in 15 minutes?

Answer 1

75

Explanation:

Set up a proportion

`(words)/(minute)` =
`(words)/(minute)`

`(100)/(20)` =
`(x)/(15)`

You can simplify
`(100)/(20)` =
`(5)/(1)` (Divide the numerator and denominator by 20)

`(5)/(1)` =
`(x)/(15)`

1 x 15 = 15

5 x 15 = 75
