So, you want to buy that Ferrari? 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', and that 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 you do not want the whole amount, hence the zero. You just want 25% of the whole which is 1.
This works for any percentage, have a look:
10% of 625 is 625 x 0.10 = 62.50
15% of 328 is 15 x 0.15 = 49.40
53% of 497 is 497 x 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 such as 17.5%, you should use the multiplier 0.175.
