Tenths

When we split a whole into ten equal parts, each part is called a tenth.

For example,

Here, a chocolate bar is split into ten equal parts. Each part is one out of ten equal parts. Hence, each part is called ‘one tenth’.

Tenth as Fraction
Here, a bar is split into 10 equal parts.

Out of 10, 1 part is shaded.
Fraction of the shaded part = $\frac{1}{10}$
So, ‘one tenth’ as a fraction is ‘$\frac{1}{10}$

Out of 10, 4 parts are shaded.
Fraction of the shaded part = $\frac{4}{10}$

Tenth as decimal
One-tenth is the same as $\frac{1}{10}$

The fraction bar between numerator and denominator is the same as the division bar.

$\frac{1}{10}$ is same is 1 ÷ 10 which is 0.1

So, ‘one tenth’ is 0.1.

Also, the first digit to the right of the decimal point represents tenths.

Example:

As a fraction = $\frac{3}{10}$
