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!

36 percent of 3600 = 1296 36% of 3600 = 36% * 3600 = 36%/100% * 3600 = 0.36 * 3600 = 1296
Plus six percent of what number? If it's six percent of 3600, you use 6 divide by 100 equals to 0.06. Then 0.06 times 3600 which is the six percent of 3600. Then you do the math for 3600 plus six percent of 3600.
