I don’t kno how to estimate using benchmarks but I kno the exacts answer is 13/10 or 1.3
Stick change flip
5/6 x 10/3 = 50/18 2 14/18 simplify 2 7/9
You need 105 children to meet the minimum.
2 x 10 4th power - 7 3rd power
2 x 10,000 - 343
20,000 - 343
19,657
I think this is the answer to your problem. Hope this helped!
