Answer 1

Answer:

n = 2.6

Step-by-step 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.

• $\frac{15}{39} = \frac 1n$

Solve for n

• $\frac{15}{39} = \frac 1n$
• $\frac{5}{13} = \frac 1n$
• $5n = 13$
• $n = \frac{13}{5}$
• $n = 2.6$

The value of n is 2.6.
