Answer:
Step-by-step explanation:To find the percentage of sixth graders with red hair at Kieran school, we need to calculate the proportion of sixth graders with red hair out of the total number of sixth graders and then convert it to a percentage.
1. Total number of sixth graders in Kieran school = 456.
2. Number of sixth graders with red hair = 108.
To find the percentage of sixth graders with red hair:
- Divide the number of sixth graders with red hair by the total number of sixth graders.
- Then, multiply the result by 100 to get the percentage.
Calculation:
\( \text{Percentage of sixth graders with red hair} = \left( \frac{108}{456} \right) \times 100 \).
\( \frac{108}{456} \) simplifies to \( \frac{3}{4} \) as both numbers are divisible by 4.
Substitute and calculate:
\( \left( \frac{3}{4} \right) \times 100 = 75 \).
Therefore, 75% of the sixth graders at Kieran school have red hair.
