%281%2F8%29%2AB+=+6
Is this it?
If so, multiplying both sides of an equation by a number
(any number) doesn't change the truth of the equation, so
multiply both sides by 8
8%2A%281%2F8%29%2AB+=+8%2A6
Note that 8%2A%281%2F8%29+=+1
B+=+48 answer
-------------------------------------------------------
On the other hand, if the problem is 1%2F8B+=+6
you should multiply both sides by 8B
8B%2A%281%2F8B%29+=+8B%2A6
1+=+48B
Now divide both sides by 48
1%2F48+=+%2848%2F48%29%2AB
Note that 48%2F48+=+1
B+=+1%2F48 answer
