# Partition numbers with decimals in tenths or hundredths

Lesson

Partitioning numbers means breaking numbers down in to two or more parts (or splitting them into smaller units).

To do this, we must understand the value of each digit in a number. In Working with tenths, we looked at the Tenths place value column, which came after the decimal point. In Working with hundredths, we looked at the Hundredths column, which came after the Tenths column.

There are different ways of partitioning a decimal number. For example, 0.49 is equal to

• 4 tenths and 9 hundredths (0.4 + 0.09)
• 2 tenths and 29 hundredths (0.2 + 0.29)
• 35 hundredths and 14 hundredths (0.35 + 0.14)

- $\frac{1}{10}$110 because 10 flats = 1 block.  [This can also be written as 0.1]
- $\frac{1}{100}$1100 because 100 cubes = 1 block.  [This can also be written as 0.01]
