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
