Solve like this: 800/680=x/100 so x=800(100)/680 = 20(100)/17 = 117.647(05882...)% Round as you see fit.
680
800 minus 15 percent = 680
Well, isn't that a happy little math problem we have here! To decrease 800 by 15 percent, we simply multiply 800 by 0.15 (which is 15 percent as a decimal), giving us 120. So, the result is 800 - 120 = 680. Just like painting a beautiful landscape, math can be a peaceful and rewarding experience when you take it one step at a time.
first you find 15% of 800. 800/100 is 8, x15 = 120. 800-120 is 680
800 * 15% = 800 * 0.15 = 120 That means 15 percent off of 800 would be 680

700.
800 * 0.85 = 680 680 * 0.8 = 544 800 - 544 = 256 256 / 800 = 0.32 = 32% 100 - 32 = 68% of the original price
You can solve this a couple different ways: 1. You can estimate that 823 is close to 800 and 680 is close to 700. Multiplying these gives you: 800 x 700 = 560,000 2. You can estimate that 823 is close to 825 and 680 is close to 675. Multiplying these gives you: 825 x 675 = 556,875 Remember that estimating does not mean you are supposed to get the actual answer (which in this case is 559,640)--you are just trying to be close. The first estimate above could be done in your head (if you remember that 8 x 7 is 56 and then just add the zeros).
