Things to remember:

$\dfrac{1}{4} = 0.25$

$\dfrac{1}{2} = 0.5$

$\dfrac{3}{4} = 0.75$

Money is made up of two parts, pounds and pence, and can be written as a decimal. So, money can be written in two ways:

£5 and 23p or £5.23

The nicest fraction out of the three is $\dfrac{1}{2}$.

We know that two 50p coins is the same as having a £1, so half of £1 is 50p. We can write 50p as a decimal like this:

50p = £0.50

So, we can say:

$$\frac{1}{2} = 0.50=0.5$$

Now, moving on to $\dfrac{1}{4}$.

If I cut a cake in half, but I wanted to cut it into quarters, so I wanted 4 pieces, what would I do to it next? Cut it in half again! So, to get a quarter of £1, we need to cut the 50p in half again.

Half of 50p is 25p, and 25p as a decimal is £0.25, so we can write a quarter as:

$$\frac{1}{4} = 0.25$$

Finally, let’s move on to $\frac{3}{4}$.

We just saw that $\frac{1}{4} = 0.25$, but we don’t want 1 of them we want 3:

$$\frac{1}{4}+\frac{1}{4}+\frac{1}{4}=\frac{3}{4}$$

$$0.25+0.25+0.25=0.75$$

So, we can say:

$$\frac{3}{4} = 0.75$$
