What is Percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred.

As per the given data:

The table gives us the data on male, female and total drivers with respect to the car they drive.

For percent of males that drive sports cars:

= (males who drive sports car / total male drivers) × 100

= (39/60) × 100

= 65%

For percent of all drivers that are male:

= (male drivers / total drivers) × 100

= (60/240) × 100

= 25%

For percent of sports car drivers that are male:

= (male sports car drivers / total sports car drivers) × 100

= (39/84) × 100

= 46.42%

Question 1 and question 3 are not the same.

Hence, the answers are as follows:

Q1: 65%

Q2: 25%

Q3: 46.42%

Q4: No
