Question

anna can type 123 in 3 minutes ,caroline can type220 words in 5 minutes who can type faster

Answer 1

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.

Answer 2

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: $\frac{220}5} = \frac{660}{15}$
Anna: $\frac{123}{3} = \frac{615}{15}$

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