The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely $a \ and \ b$ , so the ratio can be written as:

$r=\frac{a}{b}$

If we can change this number without changing the ration we need to multiply both the numerator and the denominator by the same number. For instance, if we have the following ratio:

$r=\frac{2}{3}$

We can multiply both the numerator and denominator, say, by 7. Then:

$r=\frac{7\times 2}{7 \times 3}=\frac{14}{21}$

As you can see, the ratio's number has changed but without changing the ratio itself because:

$\frac{2}{3}=\frac{14}{21}$

The restaurant would have to give the free samples to its customers so that they would provide a feedback for the business.

<h3>What is feedback?</h3>

This is the word that is used to refer to the information that one has to create or give as way of reacting to the use of a product or of a new service.

This is a way of bringing about improvements or about bringing a new line into a new market. The customers in this case would have to tell the restaurant what they think about the new dish.
