$1 = €0.93. Change €100 to dollars.

Step by step

The question

Question: change €100 to dollars, when $1 = €0.93.

1 Write the rate

The rate says: 1 dollar is worth 0.93 euros.

From dollars to euros, we multiply by 0.93.

Going back, we divide by 0.93.

2 Divide by the rate

Each $1 gives €0.93.

So we find how many €0.93 fit in €100: we divide by 0.93.

Careful!

From euros back to dollars goes the other way.

We divide, not multiply.

100 divided by 0.93 is about $107.53.

To divide by 0.93, we move the point in both numbers 2 places: 10000 divided by 93.

Money goes to the cent.

So €100 is about $107.53.

3 Check

Let's check: change the answer back.

$107.53 times 0.93 is about €100.

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.
