Answer:
n = 18
Step-by-step explanation:
[tex] \frac{6}{5} = \frac{n}{15} [/tex]
Cross multiply and simplify
[tex]6 \times 15 = 5 \times n \\ 90 = 5n[/tex]
Divide both sides of the equation by 5
[tex] \frac{90}{5} = \frac{5n}{5} [/tex]
Simplify : Cross cancel common factor: 5
[tex]18 = n \\ n = 18[/tex]
