Problema Solution
The ratio of boys to girls in Jake's computer club is 6:8. How can you estimate the percent of in the club?
Answer provided by our tutors
Let
b = the number of boys
g = the number of boys
b : g = 6 : 8
8b = 6g
b = (3/4)g
The percentage of boys is:
b/(b + g) = (3/4)g/((3/4)g + g) = (3/4)/(7/4) = 3/7 = 0.43 or 43% approximately
The percentage of girls is:
100 - 43 = 57% approximately
There are about 43% boys and 57% girls in the club.
