25000 = 250 x 100, so 21% = 250 x 21...
(7 percent of 21) - (4 percent of 21) = 0.63
(24/100) x 21 = 5.04

21% of 1,300= 21% * 1300= 0.21 * 1300= 273
21 x 115/100 ie 24.15
25000 = 250 x 100, so 21% = 250 x 21...
It is: 12% of 175 = 21
(7 percent of 21) - (4 percent of 21) = 0.63
86*0.21=18.06 or (21/100)*86 = 18.06
(24/100) x 21 = 5.04
The percent of oxygen is 27. this increases the natural percent of 21 by 6 percent causing living organisms to have too much oxygen.
