 02-20-2007 #2 Temperal Guest   Posts: n/a Multiply everything by 100. 60-22=38 Then, divide the answer by 100. 0.38 Do the others by yourself. Of course, you don't have to do this, but you probably will have trouble otherwise.

 02-20-2007 #5 Temperal Guest   Posts: n/a Huh? Wait, no. 0.5 times 100 is 50. 0.12 times 100 is 12. If you have 0.5-0.12, you then get 50-12. Then, once you do the minusing (bad grammar), you get 38. 38 divided by 100 is 0.38. Get it?
