### Theory:

The second digit which placed after a decimal point is called the hundredth place. The hundredth place is $\frac{1}{100}$.

We can also show decimals using blocks.
1. Hundreds block have $$100$$ boxes.

2. Tens block have $$10$$ boxes.

3. Ones block have $$1$$ box.

4. Tenths block have $\frac{1}{10}$ boxes of ones block.

5. Hundredths block have $\frac{1}{100}$ boxes of ones block.

In the above image:

$$2$$ hundreds box + $$3$$ tens box + $$5$$ ones box + $$4$$ tenths box + $$2$$ hundredths box

$200+30+5+\frac{4}{10}+\frac{2}{100}=235.42$

This number can be read as "two hundred thirty-five and forty-two hundredth".

It also can be read as "two hundred thirty-five point four two".

This also can be represented in the place value table.

The third digit which placed after a decimal point is called the thousandth place. The thousandth place is $\frac{1}{1000}$.
Important!
$\frac{1}{100}$ means $$1$$ part out of $$100$$ parts of a whole.

$\frac{1}{1000}$ means $$1$$ part out of $$1000$$ parts of a whole.
