Math question ..a/(b*c*d)=e/f how do i find b?

hi i was just wondering how i can get b alone on its side to find an answer.


a/(b*c*d)=e/f.

Math question ..a/(b*c*d)=e/f how do i find b?
If a / bcd = e / f, then bcd / a = f / e. (Use the property of proportions: the product of the means equals the product of the extremes.) Either way a x f = (bcd) x e.





If bcd / a = f / e, then bcd = af / e. (Multiplying both sides by a.)





Now multiply both sides by 1 / cd. (This is the same as dividing both sides by cd.) So b = af / ecd.
Reply:a/(b*c*d)=e/f


af/cde=b
