In Lesson 49 (pages 96-97) of Level E, I am to mark a certain point on a meterstick and the child is to give the answers in both tenths and hundredths. What would be the proper way to list 82/100 in tenths? Do we use a decimal point in the numerator or a remainder? My son was wondering. (The same question goes for 68/100 and 173/100.) Thanks!
