Introduction

In this article, we will delve into the world of mathematics and solve a problem related to the track and field team. The problem states that $\frac{4}{5}$ of the total track and field team members do the long jump. We are given that there are 40 members on the track team, and we need to find out how many members do the long jump.

Understanding the Problem

Let's break down the problem and understand what is being asked. We are given a fraction $\frac{4}{5}$ , which represents the proportion of team members who do the long jump. This means that out of every 5 team members, 4 of them do the long jump. We are also given the total number of team members, which is 40.

Calculating the Number of Long Jumpers

To find the number of team members who do the long jump, we can multiply the total number of team members by the fraction $\frac{4}{5}$ . This will give us the number of team members who do the long jump.

\text{Number of long jumpers} = \frac{4}{5} \times \text{Total number of team members}

Substituting the Values

Now, let's substitute the values into the equation. We know that the total number of team members is 40, so we can substitute this value into the equation.

\text{Number of long jumpers} = \frac{4}{5} \times 40

Simplifying the Equation

To simplify the equation, we can multiply the numerator and denominator by 40.

\text{Number of long jumpers} = \frac{4 \times 40}{5 \times 40}

Cancelling Out the Common Factors

Now, let's cancel out the common factors in the numerator and denominator.

\text{Number of long jumpers} = \frac{160}{200}

Reducing the Fraction

To reduce the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 40.

\text{Number of long jumpers} = \frac{160 ÷ 40}{200 ÷ 40}

Simplifying the Fraction

Now, let's simplify the fraction.

\text{Number of long jumpers} = \frac{4}{5}

Conclusion

In conclusion, we have solved the problem of finding the number of team members who do the long jump. We used the fraction $\frac{4}{5}$ to represent the proportion of team members who do the long jump, and we multiplied this fraction by the total number of team members to find the number of long jumpers. The final answer is $\boxed{32}$ .
