Introduction

In this article, we will explore the concept of fractions and percentages in the context of a simple survey. We will calculate the fraction of people who say "yes" and the percentage of people who say "yes" based on the results of a survey of 50 people.

Calculating the Fraction of People Who Say "Yes"

To calculate the fraction of people who say "yes," we need to divide the number of people who say "yes" (44) by the total number of people surveyed (50).

Fraction = Number of people who say "yes" / Total number of people surveyed

Fraction = 44 / 50

To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 44 and 50 is 2.

Simplified fraction = (44 ÷ 2) / (50 ÷ 2)

Simplified fraction = 22 / 25

Therefore, the fraction of people who say "yes" is 22/25.

Calculating the Percentage of People Who Say "Yes"

To calculate the percentage of people who say "yes," we need to convert the fraction to a percentage by dividing the numerator by the denominator and multiplying by 100.

Percentage = (Numerator ÷ Denominator) × 100

Percentage = (22 ÷ 25) × 100

To simplify the calculation, we can first divide 22 by 25, which gives us 0.88. Then, we can multiply 0.88 by 100 to get the percentage.

Percentage = 0.88 × 100

Percentage = 88%

Therefore, the percentage of people who say "yes" is 88%.

Conclusion

In this article, we calculated the fraction and percentage of people who say "yes" based on the results of a survey of 50 people. We found that the fraction of people who say "yes" is 22/25, and the percentage of people who say "yes" is 88%.
