It is: 600-96 = 504
420
20% of 80 is 16 and 80-16= 64
700 decreased by 49 percent = 357
300 decreased by 17 percent = 249
First 100 percent is 600, so 200 percent is 1200, 300 percent 1800. Then 60 percent of 600 is 360. so 360 percent of 600 is 2160.
420
16% of 600 = 16% * 600 = 0.16 * 600 = 96
It is X*0.21 - 16
The result is 600 seconds or a decrease of 150 seconds.
6.4
75% decrease.
Think of it this way, what is 16 percent of 100? 16, take 16 times 6 = 96
20% of 80 is 16 and 80-16= 64
20% = 1/54 + 4 + 4 + 4 + 4 = 2020 decreased by 20% is 16, therefore the answer is 20
20
16% = 16/100 = 0.16 400 x 0.16 = 64 400 - 64 = 336
500 x 0.84 = 420 percent. I hope this helps because I am only in year seven.
