If you don't you risk never getting the color out or it fading too quickly.
The average of 82 percent, 94 percent, 89 percent, and 91 percent is 89 percent.
(85 percent + 79 percent + 92 percent + 100 percent)/4 = 89 percent
30 percent of 20 percent of 150 percent = 0.09
(21 percent) + (32 percent) + (76 percent) + (95 percent) = 2.24
0.900 percent = 0.90 percent = 0.9 percent = 9/10 percent 0.900 percent = 0.009 0.900 = 90 percent
(75 percent) percent of 42 = 31.5%
