25% increase.
It means that only 20% of the humidity of 100% is in the air.
25%
% change = (final # - original #)/original# * 100%(140-80)/80 * 100% = 75% increase
To convert 80% to a decimal divide by 100:80 ÷ 100 = 0.8
It is: 80% => 80/100 = 4/5 simplified
First, change 80% to a decimal by dividing by 100, which is 0.8. Then multiply 100 by 0.8 which results in 80 as the answer.
40%% change =|original value - new value|/original value * 100%= |80 - 48|/80 * 100%= 32/80 * 100%= 0.40 * 100%= 40% (decrease)
First, change the percent to a decimal which is done by dividing by 100. Then, multiply that result by 80:40 / 100 = 0.40.4 x 80= 32
12.8 To find it you just change the percent to a decimal and multiply it by the number. (ex. 0.16*80=12.8)
80% = 80/100 = 4/5
80 percent of one hundred = 8080% of 100= 80%/100 * 100= 80
Percent means part of a hundred. So to change any percent into a fraction, divide it by 100. In this case we have 80/100 or 8/10 which is the same as 4/5.
