**Introduction:**

We are often required to compare two quantities in our daily life. They may be heights, weights, salaries, marks etc.

To compare two quantities, the units must be the same.

Two ratios can be compared by converting them to like fractions.

If the two fractions are equal, we say the two given ratios are equivalent.

If two ratios are equivalent then the four quantities are said to be in proportion.

A way of comparing quantities is percentage. Percentages are numerators of fractions with denominator 100. Per cent means per hundred.
