2. Important Terminology Divisor-the number you are dividing Dividend-the number you are dividing by

3. Dividing with Decimals: There are 2 types of division problems involving decimal points: No decimal in the divisor Decimal in the divisor

4. Division with Decimals: NO decimal point in the divisor… Step 1: Write the problem in the traditional long division format Step 2: Move the decimal point in the dividend straight up into the quotient Step 3: Divide as usual Remember to divide out one more place than you are rounding to…

5. Division with Decimals: NO decimal point in the divisor… 2.127 24.254 - 4 02 -2-2 05 -4-4 14 -14 0 Move the decimal point straight up and divide

6.
