Today we're going to have a look at tenths - and the different ways of showing tenths.

What is a tenth? Well, if you chop a whole unit into 10 equal bits, one of those bits is called one tenth. Make sense so far? Good. Two of those bits is two tenths, three of those bits is three tenths, and so on.

As well as writing them as words, you can show them in diagrams, numbers and fractions.

So one tenth as a decimal number is;

 

0.1 

 

That 0 shows that we've no units - the decimal point there separates tenths and units as it always does, and the 1 is under the tenths place value, to show there's one tenth.

 

As a fraction, it's

1⁄10

 

The ten on the bottom is how many bits we've divided into - 10. The 1 is how many bits we've got - 1 of those tenths. 

So 1⁄10 and 0.1 are exactly the same number, just different ways of showing it. Have a look at this BBC bitesize video for more on converting tenths into fractions and the other way round;

Have a go at the work below - you've got to match the ones on the left to the ones on the right. Remember a whole unit is the same as ten tenths, no matter if you write it 1.0 or 10⁄10!
