Question

Jason takes 2 centiliters of medicine. how many milliliters is this

Answer 1

Always when moving from centiliters to milliliters, you multiply by 10.
Which mean 1 centiliter = 1 * 10 milliliter = 10 milliliter 
So we get:
2 centiliters = 2 * 10 milliliters = 20 milliliters. 

Which means Jason takes 20 milliliters of Medicine.

Hope this Helps :)
