Fractions

The value of a fraction is the same as the value of an equivalent fraction.

You can find the equivalent to a fraction by multiplying the numerator and the denominator by the same number:

frac{a}{b}=frac{a*c}{b*c}

For example, we want to find the equivalent fraction of:

frac{1}{3}

by multiplying the numerator and the denominator by 5.

frac{1}{3}=frac{1*5}{3*5}=frac{5}{15}
