Answer :
Robert has a 16 oz bottle of water and he drinks 9 ounces from it. Robert has approximately 43.75% of his water left in the bottle.
To calculate the percentage of ounces Robert has left, we can use the formula:
Percentage = (Amount left / Total amount) * 100
The amount left is the total amount minus the amount consumed. In this case, the total amount is 16 ounces and the amount consumed is 9 ounces.
Amount left = 16 - 9 = 7 ounces
Now, let's calculate the percentage:
Percentage = (7 / 16) * 100 ≈ 43.75%
To understand this better, let's consider an example. If you have a pizza with 8 slices and you eat 3 slices, the number of slices left would be 8 - 3 = 5 slices.
The percentage of slices left would be (5 / 8) * 100 ≈ 62.5%.
In a similar way, we calculated the percentage of ounces left in Robert's water bottle.
