Answer
n=1.56
Work Step by Step
Use cross products to solve for n.
$\frac{7.8}{13}=\frac{n}{2.6}$ $\longrightarrow$set cross products as equal
$7.8\times2.6=13n$ $\longrightarrow$multiply
$20.28=13n$ $\longrightarrow$multiplication property of equality
$20.28\div13=13n\div13$ $\longrightarrow$divide
$1.56=n$
