Question

In 5 min Peter completed 2 math problems. Yvonne said he did 3/5 of a problem each minute. Is she correct ? Explain. 

Answer 1

First, we find out how many problems he did in one minute.  Divide 2 by 5.

 

2 problems / 5 min = (2/5) problems per minute

 

 

So for each minute, Peter completes 2/5 of a problem and not 3/5 of problem.   Yvonne is incorrect.
