These might be be the actual numbers, but this is not a correct ratio because there is a common factor of $3$

Divide both values by $3$

$\text{ "15/3" ":" "3/3" }$

$\text{ "5" ":" "1" }$

The following ratios are all equal, but they are not in simplest form.

$\text{ "25" ":" "5" }$

$\text{ "60" ":" "12" }$

$\text{ "10" ":" "2" }$

$\text{ "50" ":" "10" }$
