Start with
[tex]\dfrac{n}{5}=\dfrac{45}{75}[/tex]
Multiply both sides by 5:
[tex]n = \dfrac{45\cdot 5}{75} = \dfrac{45}{15} = 3[/tex]
Answer:
n = [tex]\frac{9}{5}[/tex]
Step-by-step explanation:
Simplify the fraction on the right side
[tex]\frac{n}{5}[/tex] = [tex]\frac{45}{75}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5n = 15 ( divide both sides by 5 )
n = 3
