Work out 17.5% of £240.

Step by step

The question

Question: work out 17.5% of 240.

1 Percent

Percent means out of 100.

So 17.5% is 17.5 divided by 100.

That is 0.175.

2 Times and divide

"Of" means times.

Now we forget the points and multiply: 175 × 240 = 42000.

Now we put the point back.

0.175 has 3 digits after the point.

240 has no digits after the point.

Together: 3 + 0 = 3.

So the answer has 3 digits after the point.

We start at the end of 42000.

The point jumps 3 places to the left: 42.000.

So we get 42.000, which is 42.

So the answer is 42.

Let's look back.

First: percent.

Last: times and divide.
