Asked by Karl

my P.E. teacher asked the 100 seventh graders in my school if they could swim. Half of the boys and two thirds of the girls said yes. Seventeen boys said no. How many seventh graders know how to swim?


Answered by Don
17(2) = 34 amount of boys
100 - 17(2)= 66 amount of girls

1/2 * 34 = 17 boys said yes

2/3 * 66 = 44 girls said yes

44 + 17 = 61 people in total know how to swim

your answer is 61
