Introduction

In this article, we will delve into the world of mathematics and explore a simple yet intriguing problem involving a basket of bananas. We are given that out of 80 bananas in a basket, 16 of them are bad. Our goal is to determine what fraction of the original number of bananas are good. This problem may seem straightforward, but it requires a clear understanding of fractions and basic arithmetic operations.

Understanding the Problem

Let's break down the problem and understand what we are trying to achieve. We have a total of 80 bananas in the basket, out of which 16 are bad. This means that the remaining bananas are good. Our objective is to find the fraction of the original number of bananas that are good.

Calculating the Number of Good Bananas

To find the number of good bananas, we need to subtract the number of bad bananas from the total number of bananas. This can be calculated as follows:

80 (total bananas) - 16 (bad bananas) = 64

So, there are 64 good bananas in the basket.

Finding the Fraction of Good Bananas

Now that we know the number of good bananas, we can find the fraction of the original number of bananas that are good. To do this, we need to divide the number of good bananas by the total number of bananas.

64 (good bananas) ÷ 80 (total bananas) = 0.8

However, we want to express this fraction in its simplest form. To do this, we can divide both the numerator and the denominator by their greatest common divisor (GCD). In this case, the GCD of 64 and 80 is 16.

64 ÷ 16 = 4 80 ÷ 16 = 5

So, the fraction of good bananas is 4/5.

Conclusion

In this article, we have solved the problem of finding the fraction of the original number of bananas that are good. We started by understanding the problem and breaking it down into smaller steps. We then calculated the number of good bananas by subtracting the number of bad bananas from the total number of bananas. Finally, we found the fraction of good bananas by dividing the number of good bananas by the total number of bananas and expressing it in its simplest form.
