So, you want to buy that sports car?
Well, that requires quite a lot of saving up!
You'll need to start putting some money away from that part-time job of yours.
You can't save it all as you want some money for other things, so the best thing to do is to save a percentage of your earnings.
Remember, percent just means out of 100, so 100% means the full amount.
This month you've been paid £320 and you can afford to save 25% of this.
Grab your calculator: input 320 and multiply by this by 0.25.
Did you get £80?
0.25 means we do not want to find the whole amount, hence the zero.
We just want 25% of the whole (which is 1).
This works for any percentage, let's take a look:
10% of 625 = 625 × 0.10 = 62.50
15% of 328 = 15 × 0.15 = 49.40
53% of 497 = 497 × 0.53 = 263.41
When finding a percentage that is less than 10, you can use multipliers such as 1% = 0.01, 2% = 0.02, 3% = 0.03, etc.
When finding a percentage that is over 10, such as 17.5%, you should use the multiplier 0.175.
In this activity, we will find percentages of amounts by multiplying using a decimal.
You will want to have a calculator handy to help you, as these questions are designed to test your understanding of this process, not your mental maths.
