It is in decimal form, can you give a little more feedback as to what you are applying?
X=46.2
_____________________________
99.2 + 62 = 161.2
180 -161.2 = 19.8
19.8 + 112 = 131.8
180 - 131.8 = 48.2
48.2 - 2 = 46.2
40/1 = 80/2 = 120/3 = 160/4 = 200/5 = 240/6 = 280/7 = 320/8 = 360/9 = 400/10 = 440/11 = 480/12 = 520/13 = 560/14 = 600/15 = 640/16 = 680/17 = 720/18 = 760/19 = 800/20
If that helps?
