Answer:
48 members
Step-by-step explanation:
Add the numbers in the ratio: 4+4=8
Divide: 24boys/4=6
Multiply: 6*8=48
Now we know there are 48 people. Take it a step forward..how many girls?
EASY!
4*6=24 girls
We know this works because 24+24=48
*Note: the 4's come from the ratio*
The value of x is 72
Each side increased by 20%
All you do is multiply 22 times 8 which is 176 then you multiply 8*4
Number of combinations is equal to the product of the number of choices for each choice....
5*3=15 combinations
