Hi!
To solve this we can set up a proportion and cross multiply.

33 x 100 = 3300
3300/30 = 110
The answer is 110%
Hope this helps! :)
Hi, Deedee. I am quite confused with the numbers that you've given because they don't add up to 100. Nevertheless, if by 'this', you mean the Thanksgiving culture, then you would just count the English and the Native American heritage. This is because the first Thanksgiving dinner was shared between the English colonists and the Native American tribes.
I hope I was able to help you in a way. Have a good day.
