A cafe employs eighteen girls and twelve boys to wait at table.
Another six boys and nine girls work in the kitchen
a) What fraction of the kitchen staff are girls?
b) What fraction of the employees are boys?
a) The total number of kitchen staff is 6 + 9 = 15. The number of girls working in the kitchen is 9. Therefore, the fraction of kitchen staff that are girls is 9/15 or 3/5.
b) The total number of employees is 18 + 12 + 6 + 9 = 45. The number of boys employed is 12 + 6 = 18. Therefore, the fraction of employees that are boys is 18/45 or 2/5.
a) To find the fraction of the kitchen staff that are girls, we need to add the number of girls working in the kitchen and divide it by the total number of kitchen staff.
Number of girls working in the kitchen = 9
Total number of kitchen staff = 9 girls + 6 boys = 15
Fraction of the kitchen staff that are girls = Number of girls working in the kitchen / Total number of kitchen staff
Fraction of the kitchen staff that are girls = 9 / 15
Fraction of the kitchen staff that are girls = 3/5
Therefore, 3/5 of the kitchen staff are girls.
b) To find the fraction of employees that are boys, we need to add the number of boys working both at the tables and in the kitchen and divide it by the total number of employees.
Number of boys working at tables = 12
Number of boys working in the kitchen = 6
Total number of employees = 18 girls + 12 boys + 9 girls + 6 boys = 45
Fraction of employees that are boys = Number of boys working at tables + Number of boys working in the kitchen / Total number of employees
Fraction of employees that are boys = 12 + 6 / 45
Fraction of employees that are boys = 18 / 45
Fraction of employees that are boys = 2/5
Therefore, 2/5 of the employees are boys.
