A class has 158 students. 1/11 of them are girls and 1/7 are boys. How many girls are in the class and how many boys are in the class?
158 students x (1 girl/11 students) = 14 girls.
158 students x (1 boy/7 students) = 23 boys.
Since 1/11 and 1/7 do not add up to 1, you cannot find exactly what gender the rest of the kids are.
