With numbers that are multiples of ten, you can drop an equal number of 0's from each number instead of doing actual division. Since percentages are measured as parts of 100, you would drop one 0 from 1000 and one 0 from 600, leaving 60 out of 100 or 60%.
25% of 1000 = 1000*25/100 = 250 40% of 600 = 600*40/100 = 240
60 percent.
40% off 1000 = 60% left of 1000 = 1000*60/100 = 600
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.
-400
0.01% of 600 is 0.06
19.5% of 600= 19.5% * 600= 0.195 * 600= 117
2 percent of 1000 would be 20.
6 = 600%
