• A tenth  is each of the parts obtained by dividing the unit into ten equal parts. It is 1:10 = 0.1
• A hundredth is each of the parts obtained by dividing the unit into a hundred equal parts, that is, a tenth into ten parts. It is 1:100 = 0.01
• A thousandth is each of the parts obtained by dividing the unit into a thousand equal parts, that is, a tenth into a hundred parts or a hundredth into ten parts. It is 1:1000 = 0.001

3. ORDERING DECIMAL NUMBERS

1. Read the following paragraph

Ordering decimals means putting them in order from smallest to largest or from largest to smallest.

• Line up the decimal points.
• Compare the digits in each column, starting on the left.Write down place value headings if it helps you.
• Below we are comparing 0.459 and 0.495 to see which is bigger.

0.459 and 0.495

Both numbers have 0 units. So look in the tenths column.

Both numbers have 4 tenths. So look in the hundredths column.

0.495 has 9 in the hundredths column whereas 0.459 only has 5 in the hundredths column. (There is no need in this example to compare the thousandths column.)So 0.495 is bigger than 0.459.
