Step 1: Determine if you are going to go left or right on the staircase.
Step 2: Determine how many steps there are from milligrams to grams. 3
Step 3: Move the decimal that many places.

5. Let’s practice… 150 .2 470,000 20 cm = _________ m
.15 L = _________ mL .2
20 cm = _________ m
470,000
.47 km = _________ mm
