Strategies to solve the quotient of 1 devided by 500,000,000

Problem.

What is the quotient of 1 devided by 500,000,000?

Solution :

This problem cannot be done on the calculator most of your student use, because the answer contains more places than the display permits. It can be done manually, although the computation often leads to an error due to the large number of zeros in the answer. We might, however, examine the answers obtain by starting with a smaal divisior, increasing the divisior, and seeing if a useable pattern emerges. Notice that the recognition of a pattern strategy is used here.

The correct answer is found easily. The number of zeros after the decimal point and before the 2 is the same as the number of zeros in the divisior.
