[tex]100\% = 200[/tex]
You divide both sides by 10 to get 10%
[tex]10\% = 20[/tex]
You divide by 10 to get 1%
[tex]1\% = 2[/tex]
Now you divide by 2 to get 0.5 (or 1/2 of 1)
[tex]0.5 \%= 1[/tex]
You can find 2% by multiplying 2 to 1% and 2
[tex]2\% = 4[/tex]
Now you need to add the 10% with 0.5% and 2% which give you 12.5%.
[tex]12.5\% = 20 + 1 + 4[/tex]
[tex]12.5\% = 25[/tex]
Now you takeaway 25 from 200
[tex]200 - 25 = 175[/tex]
Decrease 200 by 12.5%
[tex]175[/tex]

25% of £200 = £50
25% divided by 2= 12.5%
£50 divided by 2 = £25
£200-£25 = £175
25% divided by 2= 12.5%
£50 divided by 2 = £25
£200-£25 = £175
