Final answer:
John has 15 badges left after giving 3/8 of them to his brother.
Step-by-step explanation:
John has a total of 24 badges. If he gives 3/8 of them to his brother, we can find out how many he has left by subtracting this amount from the total.
To calculate this, we first need to find how many badges John gives to his brother. To do this, we multiply the total number of badges by the fraction 3/8: 24 x 3/8 = 72/8 = 9.
So, John gives 9 badges to his brother. To find out how many badges he has left, we subtract 9 from 24: 24 - 9 = 15. Therefore, John has 15 badges left after giving 3/8 of them to his brother.
