Before distributing this worksheet to my students, I write a different phrase on the top of each of their worksheets (like "3 out of 10" or "29 out of 100"). Be sure to write the phrase on the coordinating worksheet (one is for tenths and one is for hundredths). Then the students fill in the rest to show different different ways to represent this quantity.
This is a nice culminating activity for fractions and decimals. It's also a nice one to display in your room!
