Decimal Multiplication and Division Practice

Here's an idea for creating your own practice problems for multiplication and division of decimal numbers.

1) Invent a decimal number with at least 4 non-zero digits. Use your favorite digits, or all of the same digits, or consecutive digits, or...  Examples: 12.34, .007777, 6544.56, etc.

2) Take a 1-digit or 2-digit number and make it into a decimal number. Examples: 0.000021, 0.6, 1.4, etc.

3) For division practice, make your number from step 1 the DIVIDEND and your number from step 2 the DIVISOR, then divide (remember the "ugly fraction" step). For multiplication practice, multiply your numbers from step 1 and step 2 together.

4) Check your answer(s) with a calculator. Did it work?? If you get REALLY stuck, take a picture or scan of your work and email it to me.
