I like to use this formula cause it's really useful when it comes to these problems:
Part Percent
________ = _________
Whole 100
So, you basically plug in the numbers into the equation, it's really easy:
??? 67%
________ = ________
850 100
Then, you cross multiply. 67% x 850 = 56,950 / 100 =
And the answer to your question is: 569.6 or rounded is 570.
