In a club of 35 boys and 28 girls, 80% of the boys and 25% of the girls have been members for more than 2 years. If n percent of the club have been members for more than 2 years, what is the value of n? Express your answer as a mixed number.

If 80% of the 35 boys have been members for more than 2 years, that means that there are 35 * .8= 28 boys. If 25% of the 28 girls have been members for more then 2 years, that means that there are 28 * .25= 7 girls. So 28+7= 35 kids out of the 35+28= 63 kids have been members for more than 2 years. 35/63= 55 5/9%.

 

 

Hope it helps!

80% of 35 is 28 and 25% of 28 is 7. That means 35 people have been memvers or more then 2 years. 35/63=5/9. The answer is 55 5/9%
