Olivia needs 54 licks for every 3 lollipops she eats. complete the table using equivalent ratios. licks lollipops 54 3 36 5

54 lick per 3 lollipops is a unit rate of 18 licks per lollipop.
36 is 2 times 18, so it needs 2 times as many licks as 18 lollipops.

36 2

I assume the last line is 5 lollipops.

If 1 lollipop takes 18 licks, then 5 lollipops take 5 * 18 licks.
5 * 18 = 90

90 5

3cm and 6 and 9 cm that a possibility of that question
