In a class of 25 students, 44% are boys. How many boys are there?

Rationale

There are 11 boys in the class.

To determine the number of boys, we calculate 44% of 25 students, which equals 11 boys. This calculation is derived from the formula: \( \text{Number of boys} = 0.44 \times 25 \).

A (10 boys) YOUR ANSWER

Calculating 10 boys implies a percentage of 40% of the total class size. To check, \( \frac{10}{25} \times 100 = 40\%\), which is less than the stated 44%. Thus, this option does not accurately represent the percentage of boys in the class.

B (11 boys) CORRECT

This option is correct as it accurately reflects 44% of the total number of students. The calculation \( 0.44 \times 25 = 11\) confirms that there are indeed 11 boys in the class, making this the right choice.

C (9 boys) YOUR ANSWER

Choosing 9 boys corresponds to 36% of the total students. To validate this, \( \frac{9}{25} \times 100 = 36\%\), which is significantly lower than the required 44%. Therefore, this choice does not meet the given percentage.

D (13 boys) YOUR ANSWER

Selecting 13 boys equates to 52% of the class size. A quick calculation shows that \( \frac{13}{25} \times 100 = 52\%\), exceeding the 44% threshold. Thus, this option is also incorrect.

Conclusion

The calculation shows that to find the number of boys in a class of 25 students at 44%, the correct answer is 11 boys. Other options fail to match the required percentage, confirming that 11 boys accurately fulfills the condition of being 44% of the total students in the class.
