First find 10% by dividing by 10. This gives 360.

Then multiply by 2 to find 20%. 360 x 2 = 720

* * * * *

True. But, in general, it is far simpler to mutiply 3600 by 20 and divide by 100 (or divide 3600 by 100 and then multiply by 20)

Thus 3600/100 = 36 and 36*20 = 720.

The above method is fine for 20% but try it with 13%.

You find 10%. Then what? Take a tenth of the 10% to get 1% and then treble it to get 3%. Finally calculate 10%+3*1%. Possible, but plentry of room for error.

Instead, all you need is 3600/100 = 36 and then 36*13 = 468!
