Money

Understanding money helps us to work out how expensive

things are and check our change when we go shopping.

Lots of systems of money (called currencies) are used around

the world. In the UK, we use currency called pounds and pence.

MEASUREMENT • MONEY MEASUREMENT • USING MONEY

So, one pound and forty-six

pence is written £1.46.

Let’s look at the items in this shop and

see how the prices have been written.

£1 is equal to 100p. We call pounds

a decimal currency, and we can think

of amounts as decimal fractions.

We don’t write £ and p together. If an

amount is more than 99p, we just write

the amount in pounds. The pence can be

written as a decimal fraction of a pound.

Converting units

of money

Converting between pounds and

pence is simple, because there

are 100p in £1. To convert pence

to pounds, we divide by 100.

To convert pounds to pence,

we multiply by 100.

An amount less than one pound

is written with the letter “p” for pence.

So, fifty-nine pence is written 59p.

To convert the other way, from

pounds to pence, we multiply

2.75 by 100 to give 275p.

To convert 275p to pounds,

we divide 275 by 100. This

gives the answer £2.75.

We write a “£” sign in front of an amount in

pounds or a “p” after amounts in pence.
