Approach:
Writing ratios as fractions:
A ratio is the quotient of two quantities. A ratio, in fact, is no different from a fraction, except that a ratio is sometimes written using colon notation other than fractional notation.
For example, the ratio of 1 to 2 can be written as
1 to 2 or

\frac{1}{2}

1 : 2

\frac{1}{2}

is called fractional notation and

1 : 2

is called colon notation.
Procedure:
In exercise 20, the ratio of the width to the perimeter of the swimming pool

= \frac{1}{5}

In this case, the numerator of ratio is 1 and the denominator of ratio is 5.
If we change the order of numerator and denominator of a ratio, it doesnt
