Question

Please help I'm confused on this question

Larry took 18 minutes to do 10 math problems. Mary took 19 minutes to do 11 math problems. Which student did more problems per minute?

(PLEASE, THERE IS NO OPTION FOR BOTH)

Answer 1

Answer:

Mary

Step-by-step explanation:

18÷10=9/5

19÷11=19/11

19/11 is greater than 9/5

Answer 2

You can think about it as problems per minute, set it up as a fraction: problems/minutes and find the answer.

Example:
Larry: 10/18= 0.5556 problems per minute
Mary: 11/19= 0.5789 problems per minute

Therefore, the answer is Mary :)
