Skill: Subtract decimals to hundredths

Line up the decimal points so that the ones, tenths, and hundredths are in the same columns.

Example:

$$5.00-2.68$$

Write the numbers in columns:

  5.00
- 2.68

Start subtracting from the hundredths place. We cannot subtract $8$ hundredths from $0$ hundredths, so we need to regroup.

• Regroup $1$ one from the $5$ ones. This leaves $4$ ones and gives $10$ tenths.
• Regroup $1$ of those tenths as $10$ hundredths. Now there are $9$ tenths and $10$ hundredths.

So, $5.00$ is now represented as $4$ ones, $9$ tenths, and $10$ hundredths:

  4  9 10
  5.00
- 2.68

Now subtract each place:

• Hundredths: $10-8=2$
• Tenths: $9-6=3$
• Ones: $4-2=2$

Therefore,

$$5.00-2.68=2.32$$

The answer is $\boxed{2.32}$.
