You divide it, and move decimal 2 places:
13/70 = 0.1857142 = 18.57142 %
In general case you multiplicate the number by 100, because % means 1/100, so if you want to have a good result you must multiplicate the result by 100, so that it stays the same. e.g.
13/70 = 13/70 times 100% = 1300/70 %. And if you divide 1300/70, you'll get the same percent 18.57142
I hope I could help, if something's unclr, add details to your question.

In these kinds of problems, always start out by taking the numerator and dividing it by the denominator.
Take 13 and divide that by 70, which will give you the decimal equivalent. Doing so will give you 13/70 = 0.1857
Now, to convert the decimal to a percentage, you need to multiply the decimal by 100%, and we will have
0.1857 X 100% = 18.57% We've essentially moved the decimal point 2 places to the right and put the % at the end.

All you have to do to convert a fraction into a percentage is to do the division
i.e 13 divided by 70. Then multiply that by 100
and you get the percentage!
13/70 = 0.1857
multiplied by 100
= 18.57 percent
or 19 percent (rounded to the nearest percent)

In order to change a fraction to a percent, divide the top number by the bottom number. When you have that answer multiply it by 100 and add a percent symbol
example) 1/3 = 1 divided by 3 = .33333..
.333.... times 100 = 33.333.....
or 33.33% or 33%
