Question

what percent of 125 is 72.9%?

Answer 1

72.9/1.25=58.23%

Answer 2

I'm sorry, your question doesn't really make sense - or is very easy. The answer to "what percent of any number is 72.9% of it" is obviously 72.9% but if you mean what is 72.9% of 125 then you can write this as \[72.9 \div 100 \times 125 = 99\]
