To solve this problem, all we have to do is to use ratio and proportion. We can create our first ratio which is:
32.5 licks / 3 lollipops
Now we can equate this ratio since this is a constant value. Let us call that the number of licks required is y, so that:
When 6 lollipops, y is:
32.5 licks / 3 lollipops = y / 6 lollipops
y = 32.5 lick * 6 lollipops / 3 lollipops
y = 65 licks
When 12 lollipops, y is:
32.5 licks / 3 lollipops = y / 12 lollipops
y = 32.5 lick * 12 lollipops / 3 lollipops
y = 130 licks
