I. Introduction
There are three ways to represent a decimal number.
Example: the number 5.1711
- Standard form — the whole decimal number:
5.1711
- Expanded form — split by place value:
5.1711 = 5 +
110 +
7100 +
11000 +
110000
- Word form — write it in words:
“Five and one thousand seven hundred eleven ten-thousandths”
Place-value reminder:
.1 = tenths · .01 = hundredths · .001 = thousandths · .0001 = ten-thousandths
