4/7=N/12 cross multiply
7N=4*12
7N=48
N=48/7
So your answer is 6 6/7 or 6.8571428
First, multiply both sides of the equation by 12. This will isolate [tex]n[/tex]:
[tex]\dfrac{4}{7} \cdot 12 = \dfrac{n}{12} \cdot 12[/tex]
[tex]\dfrac{48}{7} = n[/tex]
Our answer is [tex]\boxed{n = \dfrac{48}{7}}[/tex].
