Answer:
3 people
Step-by-step explanation:
If there are 16 people in the first lecture and 6 people have brown eyes, the ratio is 6:16. If in the next lecture there is 8 people, all that needs to be done is halving the numbers in the original ratio (to get 16 to 8). Therefore, the ratio is 3:8, meaning 3 people out of 8 would have brown eyes.
The numbers except the cubed roots are all put together to form one big number in order.
1^3+5^3+3^3 = 153
16^3+50^3+33^3 = 165033
166^3+500^3+333^3 = 166500333
1666^3+5000^3+3333^3 = 166650003333
