Ryan can text 22 words in 4 minutes. At this rate, how many words could he text in 12 minutes?

Answer 1

texting rate = ^words/_{duration of time}

number of words texted = time given • texting rate

Ryan's rate is ^{22 words}/_{4 min}. Start with the time given, 12 min, and multiply by his rate:

12 min • (^{22 words}/_{4 min}) = (min units cancel)

do the math: 12 x 22 ÷ 4 = 66

12 min • (^{22 words}/_{4 min}) = 66 words

Answer 2

This can be solved by setting up a proportion.

22 words/4 mins = x words/12 mins

For the denominator, you would need to multiply 4 by 3 to get 12, so do the same thing to the numerator.

22 x 3 = 66 words
