What's a "promble"?


Cross-multiply:  The numerator on the left times the denominator on the right (for your situation that would be 4 times X) is equal to the denominator on the right times the numerator on the left (1.60 X 12).  You end up with:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 4x\ =\ 1.6\,\times\,12]


Just solve for *[tex \Large x]
