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
Oh, dude, okay, let's break it down. So, to decrease 800 by 15 percent, you just need to multiply 800 by 0.15 (which is 15 percent in decimal form) and subtract that from 800. So, 800 - (800 * 0.15) = 680. So, the answer is 680. Easy peasy, right?
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).
