(proportions) madison completes 3 worksheets in 30 minutes, while nicole completes 4 worksheets in 20 minutes. how many more worksheets can nicole complete in 10 minutes than madison?

In 10 minutes Madison would complete 1 worksheet
In 10 minutes Nicole would complete 2 worksheets,
so she can complete 1 more than Madison

This one is fairly easy if you break it down.  You want the two pices of information to be in terms of 10 minutes, so youhave to changes them so that they are.

So M does 3 in 30 minutes. To make that into 10 minutes, we divide by 3, so we must also divide the other part by three.  The answer looks like:
3:301:10.

Right? Now N does 4 in 20.  We have to divide the 20 by 2 to get 10, so we divide the 4 by 2 as well.

4:202:10

Now check the question, and it says: How many more can Nicole do?

Nicole does 2 and Madison does only one, so

Answer is: 1 more.

Yeah she/ he needs look how long that is man
