800 * 15% = 800 * 0.15 = 120 That means 15 percent off of 800 would be 680
120/800 which reduces to 3/20
An 800 percent increase.
35 percent 800 = 28035% of 800= 35% * 800= 0.35 * 800= 280
first you find 15% of 800. 800/100 is 8, x15 = 120. 800-120 is 680
120 is 15% of 800
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.

800 * 15% = 800 * 0.15 = 120 That means 15 percent off of 800 would be 680
800 kg x 15% = 120 kg
120/800 which reduces to 3/20
An 800 percent increase.
To solve this you need to work out how big a number 1 percent of the number would be. So if 120 is 15 % then 1% = 120/15 = 8 Thus if 1 % of the number = 8, you need to make this up to 100% by multiplying by 100. 8*100 = 800 So the number is 800. I hope you can follow this and that you will now be able to work with %.
35 percent 800 = 28035% of 800= 35% * 800= 0.35 * 800= 280
42% of 800 = 42% * 800 = 0.42 * 800 = 336 or 33,600%
