Answer:
55%
Step-by-step explanation:
What we must do is get the total number of people, that is, boys and girls who have been a member for more than 2 years, that is:
children: 0.8 * 35 = 28
girls = 0.25 * 28 = 7
Now, passing knowing the%, would be dividing the sum of the above by the sum of the total club members:
(28 +7) / (35 + 28) = 0.55
Since it is a number below 1, it cannot be a mixed number.
Answer:
[tex]55\frac{5}{9}[/tex] %
Step-by-step explanation:
First we find the number of boys that have been members for more than two years:
B = 80% of 35 = 0.8 * 35 = 28 boys
Then, we find the number of girls that have been members for more than two years:
G = 25% of 28 = 0.25 * 28 = 7 girls
So, the total number of people that have been members for more than two years is:
T = B + G = 28 + 7 = 35
The total number of people in the club is:
Total = 35 + 28 = 63 people
So the percentage of people that have been members for more than two years is:
P = (T/Total)*100% = 3500/63 % = [tex]55\frac{35}{63}[/tex] % = [tex]55\frac{5}{9}[/tex] %
