Hello,

with percentages you are dealing with fractions with the constant denominator 100. You only have to transform a number into a fraction with the denominator 100 and the numerator of this fraction is this number as percent:

$2.0 = \frac{2.0 \cdot 100}{100} = \frac{200}{100} = 200\%$

$0.01 = \frac{0.01 \cdot 100}{100} = \frac{1}{100} = 1\%$
