Hello! To solve this problem, we'll need to find a common denominator and set each ratio accordingly.

Anna- 123 in 3 minutes
123:3

Caroline- 220 in 5 minutes
220:5

Both 3 and 5 can go into 15.

Caroline:
\frac{220}5} = (660)/(15)
Anna:
(123)/(3) = (615)/(15)

Anna can type faster than Caroline. Hope this helps! :)

Caroline.
If you divide 123 by 3 to see how many words Anna types per minute, its comes to 41 words/minute. Dividing 220 by 5 to find the words/minute Caroline types would result in 44 WPM.
