- Unitary method is "A way of finding a single-unit value from a multi-unit value, and then finding a multi-unit value from a single-unit value."
- For simplicity, always write what you calculate on the right and what you know on the left.
- In order to do that, we must first find the value of one thing by division and then find the value of more or fewer things by multiplication.
It is given that Colin fills 4.5 ounce per bottles .
We apply division because we need to find the cost of one item given the cost of many items. If you need to find the cost of many items from the cost of one item, apply the multiplication operation.
Using unitary method , we get
1 bottles have = 4.5 ounces
7.5 bottles will have = [tex]7.5\times 4.5=33.75[/tex] ounces
