120
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
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
120 is 15% of 800
120
8
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%
