% = 100(rate)
100(.2166) = 21.66 %
0.2166 = to find a percent from a decimal you multiply that number by 100 or move the decimal point 2 places to the right
0.2166 x 100= 21.66%
21.66 %
0.2166 x 100% = 21.66%
21.66% Simply multiply decimals by 100
Just shift the decimal two places to the right to get 21.66%
Multiply this fraction by 100.
0.2166 x 100 = 21.66 %
Assume income = x
saving = 0.2166 x
% saving = (0.2166 x/ x) × 100
= 2166 × 100 / 10000
= 21.66 %
0.2166 of their income is 21.66% of their income
Percent means
Per = out of
Cent = one hundred
So if we want to know what percent 0.2166 is, we write:
0.2166 = x %
In words, this says 0.2166 equals an unknown percent. As I just defined, % means out of one hundred, so replace % by 1/100.
0.2166 = x * (1/100)
0.2166 * 100 = x
21.66 = x
So this says 0.2166 = 21.66 %
21.66% to change a decimal to a % move the decimal @ places to the right. keep all of the numbers after the decimal unless they tell u to round.
參考: School.
0.2166 = 2166 / 10000
(2166/10000) * 100= 21.66 %
