$n=1.02$

This does work!

Turn everything upside down giving:

$n/6=0.51/3$

Don't like decimals so lets get rid of them

$color(green)(n/6=0.51/3color(red)(xx1)" "->" "n/6=0.51/3color(red)(xx100/100))$

$color(green)(" "n/6=51/300)$

Multiply both sides by $color(red)(6)$

$" "color(green)(n/6color(red)(xx6) =51/300color(red)(xx6))$

$" "color(green)(nxx cancel(6/6)=51/(cancel(3)^1xx100)xxcancel(6)^2)$

$" "color(green)(n=102/100=1.02$

How do you solve 6/n=3/0.516/n=3/0.51?
