Percent means parts out of 100
x/100=x%
roosters=6
x=percent
6/15=x/100
2/5=x/100
times both sides by 100*5
200=5x
divide both sides by 5
40=x
answer is 40%
If you are asking for a common factor of 16 AND 20 the answer can be 80

Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
