Answer:
Step-by-step explanation:
[tex]\frac{14}{7} =\frac{n}{21}[/tex]
Let us divide by 14 by 7 which is 2, so the equation is:
[tex]2 = \frac{n}{21}[/tex]
Let us multiple 21 over the other side since 21 is in the denominator of the equation, so we get
[tex]n = 21*2 = 42[/tex]
So the answer is 42.
