Calculating the Number of Red Balls

To calculate the number of red balls, we can start by finding the total number of red balls among the 80 balls given that 2/5 of them are green.

The total number of red balls can be calculated using the following steps:

1. Calculate the number of green balls: - 2/5 of 80 = (2/5) * 80 = 32 green balls 2. Calculate the number of red balls: - Total balls - Green balls = 80 - 32 = 48 red balls

So, there are 48 red balls out of the 80 balls.

Conclusion

After analyzing the given information, it can be concluded that out of the 80 balls, 2/5 of them are green, and the remaining 3/5 are red. Therefore, there are 48 red balls and 32 green balls.
