ratio = 80% : 20% or 80 : 20 ot 8 : 2 or 4 : 1
80:20
A percent is a number relative to 100. Therefore, we want the number 100 in the ratio. In order to do that, we need to multiply BOTH numbers in the ratio by a number so that the second number of the new ratio is equal to 100. The first number of the new ratio is the percent. For example: 4:5 = [4*20]:[5*20] = 80:100 = 80%
20 percent of 80 = 1620% of 80= 20% * 80= 20%/100% * 80
20 percent of 80 percent = 0.16 or 16%
20 percent of 80 percent = 0.16 or 16%
80/20 = 4/1
20 is what percent of 80:= 20 / 80= 0.25Converting decimal to a percentage:0.25 * 100 = 25%
25 percent (one-fourth) of 80 would be 20, and 20 percent of 20 is 4. So, the answer is 4.
80% of 20 is 16.
The atomic mass of hydrogen is 1 and that of carbon is 12, to the nearest integer. Therefore, a compound that contains 20 percent hydrogen and 80 percent carbon contains atoms of carbon in the ratio of 20:(80/12) = 20:(20/3) = 20 X 3/20 = 3. The smallest whole number ratio corresponding to this is 1:3, which corresponds to an empirical formula of CH3. (However, since carbon normally has a valence of 4 in hydrocarbons, the actual formula is probably C2H6.)
It is 20/80 which can be simplified, if required.
80% of 20 = 80% * 20 = 0.8 * 20 = 16
