How do you get 20 percent out of 200?You have to use this formula; is/of = %/100. That formula will give you the answer every single time!The answer is: 40.
It's anybody's guess what such a formula might look like,because 20 is not 75 percent of 15.75 percent of 15 is 11.25 .15 is 75 percent of 20 .
20 x .04 = ?
20 x .6 = 12
What percent of 20 is 2?10% of 20 is 2.The formula you can use for all the problems like this is: is/of = %/100.
450 x 0.2 = 90
16-20%
To find 6 percent of a number, multiply the number by 0.06. In this instance, 0.06 x 20 = 1.2. Therefore, 6 percent of 20 is equal to 1.2.
The empirical formula for a compound containing 20% hydrogen and 80% carbon would be CH4, which is methane. This is because the ratio of carbon to hydrogen in methane is 1:4, which corresponds to the given percentages.
The empirical formula would be CaBr2 since it contains a ratio of 1 calcium to 2 bromine atoms.
