**Cindy**, Tuesday, November 1, 2011 at 9:16pmA good way to deal with decimals is to multiply each "group" (separated by + or - signs) by the place to the right of the decimal. So for this problem, you could multiply 0.7 by 10, since it goes to the tenths place, and 168 by 10 as well, since that is another group. DO NOT FORGET TO MULTIPLY THE OTHER GROUPS!!! So your new equation would be 7x=1680. This process has worked great for me :) Just thought I'd share :)
