127.5 out of what number equals 15 out of 100 ?

 

\(\frac{127.5}{x}=\frac{15}{100} \\~\\ 127.5=\frac{15}{100}\,*\,x \\~\\ 127.5\,*\,\frac{100}{15}=x \\~\\ 850=x\)   Now we just need to solve this for x .

Let the number = N, so we have:

0.15N = 127.50  divide both sides by 0.15

N =127.50 / 0.15

N = 850
