Exercise 2 Page p21

We can use the percent proportion to rewrite the given percent as a fraction in simplest form. The percent proportion is a proportion that equates a part of a whole to a percent out of

100 .

\frac{part}{whole} = \frac{percent}{1 0 0} \Leftrightarrow \frac{a}{b} = \frac{p}{1 0 0}

By substituting

p = 60

into the formula, we can determine the fraction that is equivalent to

60 % .

\frac{a}{b} = \frac{p}{1 0 0}

Substitute

$p = 60$

\frac{a}{b} = \frac{6 0}{1 0 0}

ReduceFrac

$\frac{a}{b} = \frac{a / 2 0}{b / 2 0}$

\frac{a}{b} = \frac{3}{5}

Therefore,

60 %

is the same as

\frac{3}{5} .
