... and its value doesn't change.
By multiplying a number by the fraction 100/100,
we change only the form of the result, not the result.
n × 100/100 = n × 1 = n, any number n
Rounded off to a max. of 12 decimal places:
7/22 ≈ 31.818181818182%
Rounded off to a max. of 2 decimal places:
7/22 ≈ 31.82%
In conclusion:
(1) Divide the numerator by the denominator (2) Multiply the result by 100 and (3) Add the percent sign %
The symbols used: % percent, ÷ division, × multiplication, = the equal sign, / the fraction bar, ≈ approximately the same. Writing numbers: comma ',' - as a thousands separator, point '.' as a decimal mark.
