Answer:

N = 4

Step-by-step explanation:

Switch sides

[tex]\bold{\frac{n}{14}=\frac{\frac{1}{7}}{\frac{1}{2}}}[/tex]

Divide fractions: [tex]\bold{\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}}[/tex]

[tex]\bold{\frac{n}{14}=\frac{1\cdot \:2}{7\cdot \:1}}[/tex]

Refine

[tex]\bold{\frac{n}{14}=\frac{2}{7}}[/tex]

Multiply both sides by 14

[tex]\bold{\frac{14n}{14}=\frac{2\cdot \:14}{7}}[/tex]

Simplify

n = 4
