A school has an enrolment of 450 students.4\9 of them are girls.0•6 of the girls are below the age 8 years.How many girls are above 8 years?

4/9 * 450 = 1800/9 = 200 girls

0.4 * 200 = 80 girls are above 8 years

To find the number of girls above 8 years, we need to determine how many girls are below 8 years and then subtract that from the total number of girls.

First, find the number of girls in the school:

Number of girls = (4/9) x Total number of students
= (4/9) x 450
= 200

Next, find the number of girls below 8 years:

Number of girls below 8 years = (0.6) x Number of girls
= (0.6) x 200
= 120

Finally, subtract the number of girls below 8 years from the total number of girls to find the number of girls above 8 years:

Number of girls above 8 years = Total number of girls - Number of girls below 8 years
= 200 - 120
= 80

Therefore, there are 80 girls above 8 years in the school.
