Types of Problems
There is one type of problem in this exercise:
- Find the quotient: This problems has a division question that has decimals in both divisor and dividend. The user is asked to find the answer and provide it in the available space.
- The answers always come out to be a terminating decimal, so if user's decimal doesn't stop, they have made an error.
- To divide decimals, it is easiest to move both decimal points (the same number of spots) to eliminate the decimal in the number users are dividing by. Both decimals move the same number of spots because effectively they are multiplying numerator and denominator of a fraction by the same power of ten.
- The calculator hurts the spirit of the problem, but can be used to dramatically improve time.
- Decimals appear in every-day media to display information to consumers.
- Decimals are very common in shopping. Price tags, food labels, and receipts all contain decimals.
- At gas pumps, decimals are used to show how much gas is pumped and much it costs per gallon.
