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
Pick one:
Now, generate a number:
For this number you just generated, fill in these blanks.
Thousandths place =
Tenths place =
Hundredths place =
Ones place =
And fill in these blanks. = × 1 +
× 1/10 +
× 1/100 +
× 1/1000
And fill in these blanks. = × 1 +
× 0.1 +
× 0.01 +
× 0.001
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.
