The correct answer is: 5

To find 10% of 50, you can use a simple calculation method. First, understand that "percent" means "per hundred," so 10% can be expressed as a fraction: 10% = 10/100 = 1/10. Now, to calculate 10% of 50, you multiply 50 by 1/10: 50 × (1/10) = 50/10 = 5. Thus, 10% of 50 is 5. This confirms that the correct answer is indeed 5. It's a straightforward calculation of determining a portion based on the total amount, in this case, the total being 50. Understanding how to convert a percentage into a fraction and then applying that to a number is key to solving similar problems in the future.
