Problem Analysis

To determine the number of blue and green balls in the box, we need to use the given information:

- There are 40 balls in total. - Half of the balls are red. - The number of yellow balls is four times less than the number of red balls.

Let's break down the problem step by step to find the solution.

Solution

Step 1: Calculate the number of red balls. - Since half of the balls are red, we can calculate the number of red balls by dividing the total number of balls by 2. - Number of red balls = 40 / 2 = 20. Step 2: Calculate the number of yellow balls. - The number of yellow balls is four times less than the number of red balls. - Since four times less means one-fourth of the number, we can calculate the number of yellow balls by dividing the number of red balls by 4. - Number of yellow balls = 20 / 4 = 5. Step 3: Calculate the number of blue and green balls. - The remaining balls in the box are blue and green. - To find the number of blue and green balls, we subtract the number of red and yellow balls from the total number of balls. - Number of blue and green balls = Total number of balls - Number of red balls - Number of yellow balls = 40 - 20 - 5 = 15.

Therefore, there are 15 blue and green balls in the box.
