What is percentage?

Percentage is  a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

We have,

Mileage of old​ car \(=40\) miles per gallon

And,

Mileage of new​ car \(=38\) miles per gallon

So,

Change in mileage \(=40-38=2\) miles per gallon

Now,

Percent Change in mileage \(=\frac{2}{40} *100\)

Percent Change in mileage \(=5\%\)

i.e.

Percent decrease in mileage \(=5\%\)

Hence we can say that the percent of decrease in​ mileage will be \(5\%\).
