Question

At winstead elementary school 10.2% of the 88 boys have blue eyes and 5.3% of the 75 girls have blue eyes. What percent of the school as a whole had blue eyed students

Answer 1

Answer: ≈ 8%

Step-by-step explanation:

Total number of students = total number of boys + total number of girls

Total number of students = 88 + 75

Total number of students =  163

10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes

$\frac{10.2}{100}$ x 88 = 8.976

Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.

Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is

$\frac{5.3}{100}$ x 75 = 3.975 , therefore : 4 girls have blue eyes.

In total , 13 students have blue eyes

Therefore , to calculate the % of students that have blue eyes , we have :

13/163 x 100 = 7.975460123

Therefore : ≈ 8% of the students have blue eyes
