Question from Jeannette, a parent:

I cannot convert because of a question that throws me off. For example, A mother African elephant avg's 250 dm in height. A newborn baby African elephant avg's 89cm in height. How many cm shorter is the baby African elephant than its mother? Which one do I convert first? in order to subtract the number from the baby?

Jeannette,

The question asked is

How many cm shorter is the baby African elephant than its mother?

so I would convert the average mother elephant height from decimeters to centimeters and then subtract the average baby elephant's height of 89 centimeters.
