To find this answer, we can cross multiply. cross multiplying multiples the denominator of one fraction by the numerator of the other, and then the numerator of one fraction by the denominator of the other (a/b=c/d, cross multiply to get ad = bc.) in this case, it would be 3*8= 4*x, so 24 = 4x. divide both sides by 4 to get x = 6.
