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)
It is 80 percent or over.
80% = 80/100 = 4/5
80%=80/100=8/10=4/5.
