Introduction

In this article, we will delve into a mathematical problem involving percentages and proportions. We will use the given information to determine the number of hot wheels Haydn has of each color. The problem is as follows: Haydn has 80 hot wheels, with 30% being red, 25% being blue, and the rest being black. We will use the concept of percentages and proportions to find the number of hot wheels of each color.

Understanding Percentages and Proportions

Before we begin solving the problem, let's review the concept of percentages and proportions. A percentage is a way of expressing a value as a fraction of 100. For example, 30% is equal to 30/100 or 0.3. A proportion is a statement that two ratios are equal. For example, if we have two ratios, 2:3 and 4:6, we can say that they are proportional because 2/3 = 4/6.

Calculating the Number of Red Hot Wheels

Let's start by calculating the number of red hot wheels. We know that 30% of Haydn's hot wheels are red. To find the number of red hot wheels, we can multiply the total number of hot wheels by the percentage of red hot wheels.

Number of red hot wheels = Total number of hot wheels x Percentage of red hot wheels
= 80 x 0.3
= 24

Calculating the Number of Blue Hot Wheels

Next, let's calculate the number of blue hot wheels. We know that 25% of Haydn's hot wheels are blue. To find the number of blue hot wheels, we can multiply the total number of hot wheels by the percentage of blue hot wheels.

Number of blue hot wheels = Total number of hot wheels x Percentage of blue hot wheels
= 80 x 0.25
= 20

Calculating the Number of Black Hot Wheels

Finally, let's calculate the number of black hot wheels. We know that the rest of the hot wheels are black. To find the number of black hot wheels, we can subtract the number of red and blue hot wheels from the total number of hot wheels.

Number of black hot wheels = Total number of hot wheels - Number of red hot wheels - Number of blue hot wheels
= 80 - 24 - 20
= 36

However, we are given that the rest of the hot wheels are black, and we know that 30% + 25% = 55%. This means that 45% of the hot wheels are black.

Number of black hot wheels = Total number of hot wheels x Percentage of black hot wheels
= 80 x 0.45
= 36

However, we are given that the rest of the hot wheels are black, and we know that 30% + 25% = 55%. This means that 45% of the hot wheels are black.
