800+800=1600 800$800=640000
1/100 x 800 = 0.01 x 800 = 8 %
100%....800 62%......x x=62%*800/100%=0.62*800=496
Well 800 is divisible by 8 (100), and so is 96 (12), so we can say 896 = 800 + 96 = 8 x 100 + 8 x 12 = 8 x 112. You can divide 112 by 4: 112 / 4 = 28. And 28 = 4 x 7. So we have 896 = 8 x 4 x 4 x 7 = (2^3) x (2^2) x (2^2) x 7 = (2^7) x 7.
