Which fraction is equal to 0.20%?
回答 (21)
First, convert the percent to a decimal by dividing by 100:
0.20% / 100 = 0.002
Now, convert to a fraction:
0.002 = 2/1000
and simplify:
2/1000 = 1/500
To convert a percent to a decimal you divide by 100. Therefore, the percent has the decimal equivalent
0.0020
this is
2/1000
參考: Longtime college math teacher
1% = 1/100
this is the same thing since I all I did was add a zero to top and bottom of the fraction:
1.0% = 10/1000
0.2% = 2/1000
(if you don't understand that, just move the decimal point to the right one spot and you'll see)
2/1000 = 1/500 (simplified answer)
The correct answer is 1/500, and bad gal gave a very
clear explanation.
1/500 which equals .002
.002 X 100 = .2%
.20 / 100 = 20 / 10000 = 1 / 500
0.20% = 0.2 / 100 = 0.002 = 2 / 1000 = 2/10 % = 0.2%
therefor the fraction is equal to 0.2% is
= 0.2 / 100 = 0.1 / 50
or
= 2 / 1000 = 1 / 500
