Step by step
The question
Question: change €69 to pounds, when £1 = €1.15.
1 Write the rate
The rate says: 1 pound is worth 1.15 euros.
From pounds to euros, we multiply by 1.15.
Going back, we divide by 1.15.
2 Divide by the rate
Each £1 gives €1.15.
So we find how many €1.15 fit in €69: we divide by 1.15.
Careful!
From euros back to pounds goes the other way.
We divide, not multiply.
69 divided by 1.15 is £60.
To divide by 1.15, we move the point in both numbers 2 places: 6900 divided by 115.
So €69 is £60.
3 Check
Let's check: change the answer back.
£60 times 1.15 is €69.
That is what we started with.
So the answer is right!
Let's look back.
First: write the rate.
Then: divide by the rate.
Last: check.
