No, sir!

sabasattar · Answer

Could you please guide me through it?

herpderp · Answer

Okay so 23.1% is out of 100%
so 8,865,000 is out of x

sabasattar · Answer

I understand that part

herpderp · Answer

A proportion helps you determine how much is out of a whole

herpderp · Answer

so it would look like this: 
$$\frac{ 23.1 }{ 100} = \frac{ 8865000 }{ x }$$
