A ratio is a comparison of values. In other words, 'A ratio says how much of one thing there is compared to another one'.

Example:

There are \(2\) eggs and \(3\) cups of flour.

Ratios can be shown in a variety of ways:

- Use "\(:\) "to set the values as \(2\)\(:\)\(3\).
- Or maybe we can use the word "to" as \(2\) to \(3\).
- Or write it down as a fraction \(\frac {2}{3}\).

Proportion states two ratios (or fractions) are the same.

Example:

From the above picture, we can easily understand that \(\frac {2}{3}\) \(=\) \(\frac {4}{6}\).

Therefore, \(2\) eggs out of \(3\) cups of flour is equal to \(4\) eggs out of \(6\) cups of flour.

The ratios are the same. So, they are in proportion.
