Units, conversions, decimal places and significant figures

I feel this question has too many questions inside it, I have since made a question that just asks a single division problem called Decimals: Division (includes rounding the answer).

By powers of ten I mean a 1 followed by some 0s. The scientific notation questions will take care of the power of ten notation.

old question, way too many things in one question! I have made better questions out of each part now.

I think I prefer the other question I made called "Rounding to 0, 1, 2 and 3 decimal places"

Useful for a review of the base 10 number system before introducing different bases and also just ensuring students understand how the base 10 system works.
