How do you convert 1 decimeter to 100 mm?

Answer 1

The prefix deci- means 1/10, so a decimeter is 1/10 of a meter. The abbreviation mm stands for millimeter. The prefix milli- means 1/1000. So 1 meter is 1000 mm. A decimeter is therefore 1/10 of 1000 mm, or 100 mm.

Place two zeros after the one to change the 1 to a 100. Now cross out the decimeter and change it to mm. There, that does it. You had 1 decimeter, now you have 100 mm in its place.
