Also, note that this number does not have what is typically referred to as "decimals". We use that term for portions of a number that are **less than one. **

For example, the number 6 **and 5 tenths** would be written **6.5**

Since 5 tenths = one half, this number would be the same as 6 1/2.

Decimal places stretch out to the right in much the same way as the place value of whole numbers stretches out to the left.

So,

.1 is one ten

th.01 is one hundred

th.001 is one thousand

th.0001 is one ten-thousand

th

etc.

Whether you are in the "decimal" places or in the whole numbers, moving a number one place to the *left *makes it 10 times *larger*. Moving a number one place to the *right* makes it 10 times *smaller*. So,

moving
