Question

In 5 minuets, Peter completed 2 math problems. Yvonne says he did 3/5 of a problem each minuets. Is she correct? Explain!

Answer 1

This is a rate problem. A rate problem is a fraction of two variables. And rates are fixed so.
\[\frac{problems}{minutes}=\frac{2 problems}{5 minutes}=\frac{3/5}{1}\]
If true, then the rate is maintained and she's right.
So it comes down to, are these equal: \[\frac{ 2}{5}=\frac{ 3/5}{1}\]
or\[\frac{ 2}{5}=\frac{ 3}{5}\]

Answer 2

so she is right?

Answer 3

Well if \[\frac{2}{5}=\frac{3}{5}\]
then yes. If they are not equal, then no.
