1) Ratio means that there is a relationship between two parts, either directly proportional or inversely proportional.
So, the ratio of 5 bottles to 2 cans, means that for every 5 bottles there are 2 cans
2) In a table we can see it better. Starting from this ratio 5 : 2 we can write the following considering a proportional growth:
Directly Proportional Ratio
Bottles | Cans
5 2
10 4
20 8
This ratio can be, depending on the context inversely proportional while one grows the other diminishes:
Bottles | Cans
5 2
2.5 4
1.25 8
