n = 2.6

Explanation:

Hello!

We can create an equation with equivalent fractions. Remember that a ratio can also be represented as a fraction.

• 
  `a:b = \frac ab`

We can create two fractions that are equivalent to each other given the ratios.

• 
  `(15)/(39) = \frac 1n`

Solve for n

• 
  `(15)/(39) = \frac 1n`
• 
  `(5)/(13) = \frac 1n`
• 
  `5n = 13`
• 
  `n = (13)/(5)`
• 
  `n = 2.6`

The value of n is 2.6.
