Integers and Decimals

Place Values The place value system also help us represent small numbers. Numbers that are smaller than 1. We do this by putting a decimal point to the right of the ones position then use the positions to the right of the decimal point to represent increasingly smaller numbers.

3.14 = 3 ones, 1 tenth, and 4 one hundredths.

Or we can state it in another way.

3 + 1/10 + 4/100

  1. Pick one:         

  2. Now, generate a number:

     

  3. For this number you just generated, fill in these blanks.
    Thousandths place =    Tenths place =    Hundredths place =    Ones place =   

  4. And fill in these blanks.
      = × 1 + × 1/10 + × 1/100 + × 1/1000

  5. And fill in these blanks.
      = × 1 + × 0.1 + × 0.01 + × 0.001

  6. When you multiply a decimal number by 10 you simply move the decimal point to the right by one place. Similarly, when you divide it by 10 you move the decimal point right by one place. Now answer these questions.

      × 10 =   

      ÷ 10 =   

      × 100 =   

      ÷ 100 =   

      × 0.1 =
