I have not eaten cookies for 2 years after I lost 50 lbs.
If there are six candies in a cookie, then there are 6*12 candies in 12 cookies, or 72 candies.
{{{chips/candies = 5/2}}}. Since we know that candies = 72,
{{{chips/72 = 5/2}}}, multiply both sides by 72
{{{chips = 72*5/2}}}
*[invoke explain_simplification "chips = 72*5/2"]
