To convert to a percentage, multiply by 100:
13*100/20 = 65%
To convert to a decimal, start from the percentage and then move the decimal point two places to the left, giving
0.65.

13 Out Of 20 As A Percentage

Divide 13 by 20 to get the decimal, then multiply by 100 for the percentage. 13/20 = .65 x 100 = 65%

Transform it in an equivalent fraction. Thus,
13/20 = x/100
Crossing:
20x = 13 * 100
20x = 1300
x = 65
So,
13/20 converted into a decimal and a percentage is .65 or 65%.

Okay to go from 13/20 to a decimal, (1/20 is 0.05)
2/20 is 0.1, 3/20 is 0.15, 4/20 is 0.2, 5/20 is 0.25, 6/20 is 0.3, 7/20 is 0.35, 8/20 is 0.4, 9/20 is 0.45, 10/20 is 0.5, 11/20 is 0.55, 12/20 is .6, so 13/20 as a decimal would be 0.65
To go from 13/20 to a percent, if 13/20 is 0.65, you move the decimal over two spots to the right, therefore giving you 65%.
I hope that was a good enough answer for you, it is right, and I'm in sixth grade. BUT IT IS RIGHT I AM SO SURE THAT IT IS RIGHT!!!

Divide 13 by 20 to get the decimal
13/20 = 0.65
Multiply the decimal by 100 and attach the % symbol.
0.65 x 100 = 65%

Multiply by 100 for percentage. Move the decimal point back two spaces for the decimal. You will probably need a calculator! No I`ll do it for you. 13 x 100 = 1300. 1300 divided by 20 = 65. therefore 65%. Move the decimal point back two places and you have .65

Demical: 0.65
Now the standar way to make a percentage out of a number, such as m/n, is multiply the result of the division by 100.
That means that because 13/20 is 0.65, we multiply it 100 times and we get 65, 65%.

easy stuff...
the fraction is 13/20...
To get a decimal fugure, simply divide 13 by 20 (the clue is in the way the fraction is written!)...
To get the percentage, find out how many of the denominator (the "20") is in 100 by dividing 100 by it (in this case 100/20), then take that result and multiply it by the numerator (the "13").
I won't give the answers, but as you ca see... they are very easy to get anyway.
Enjoy!

decimal: just divide 13 by 20, you will get: 0.65
percent: you have 13/20 and you want x/100
x = 100* 13/20 = 65%
