Number - fractions

A hundredth is one of 100 equal parts. Hundredths can also be seen when each tenth is divided into 10 smaller equal parts. Counting in hundredths helps link fractions and decimals.

Tenths into hundredths

One tenth can be split into ten hundredths.

Hundredths are smaller equal parts than tenths.

Count up in hundredths

We can count $\frac{1}{100}$ , $\frac{2}{100}$ , $\frac{3}{100}$ and so on.

The denominator stays the same while the numerator changes.

One whole in hundredths

$\frac{100}{100}$ is one whole.

One whole can be named in different ways.

Worked example

What comes after $\frac{48}{100}$ when we count in hundredths?

Count in hundredths by increasing the numerator by 1.
$\frac{48}{100}$ is followed by $\frac{49}{100}$ .
The denominator stays as 100 because the whole still has 100 equal parts.
So the next fraction is $\frac{49}{100}$ .

Round 1: Learn it

Common mistakes

Watch for these as you work through the lesson.

Changing the denominator while counting in hundredths.
Forgetting that $\frac{100}{100}$ is one whole.
Mixing up tenths and hundredths.

Count up and down in hundredths; recognise that hundredths arise when dividing an object by one hundred and dividing tenths by ten
