The ratio of the number of lollipops to the number of licks indicates that the table of equivalent ratios can be presented as follows;
Number of lollipops Olivia licks Number of licks
1 18
2 36
3 54
4 72
5 90
The steps used to build the above table of equivalent ratios can be presented as follows;
The number of licks olivia needs for every 3 lollipops shwe eats = 54 licks, therefore;
The number of licks for 1 lollipop is; 54/3 = 18 licks
The table of equivalent ratios is therefore;
Number of lollipop Olivia eats Number of licks
1 18
2 36
3 54
4 72
5 90
The ratio of the number of lollipops to the number of licks is 1 : 18
