5. In a class of 25 students, 44% are boys. How many boys are there?
Answer: B
There are 11 boys in the class.
To find the number of boys in a class of 25 students where 44% are boys, we calculate 44% of 25, which results in 11 boys.
A) 10 boys
This option is incorrect because calculating 44% of 25 gives us 11, not 10. Thus, this choice does not accurately reflect the correct percentage of boys in the class.
B) 11 boys
This option is correct as it accurately represents the calculation of 44% of 25. Specifically, 0.44 multiplied by 25 equals 11, confirming that there are indeed 11 boys in the class.
C) 9 boys
This option is incorrect as it underestimates the number of boys. A calculation of 44% of 25 does not yield 9, and thus this choice misrepresents the actual figure derived from the given percentage.
D) 13 boys
This option is also incorrect because it overestimates the number of boys. The calculation of 44% of 25 results in 11, and therefore 13 is not a valid answer based on the percentage given.
Conclusion
The correct answer is 11 boys, which is determined by calculating 44% of 25 students. All other options fail to represent the accurate result derived from the percentage, either by underestimating or overestimating the actual number of boys in the class.
