There are 90 girls and 60 boys in the sixth grade at a middle school. Of these students, 9 girls
and 3 boys write left-handed. What percentage of the sixth graders at this middle school write
left-handed?
A 10%
B8%
C5%
D 15%

B: 8%

Step-by-step explanation:

It asks for percentage of total students, so we add the male and female student totals for a total of 150 students. We also add the numbers of those that are left handed for a total of 12. We divide 12 by 150 (12/150) to get the decimal, 0.08, which is 8%.
