you want to convert cups to days.
Since 2/3 cups = 1 day, 2cups = 3days, or 3days/2cups = 1
so, since you can always multiply by 1 without changing things,
5 cups * (3days)/(2cups) = 15/2 days
Since 2/3 cups = 1 day, 2cups = 3days, or 3days/2cups = 1
so, since you can always multiply by 1 without changing things,
5 cups * (3days)/(2cups) = 15/2 days
