An easy way is to pretend that 25 is positive. 14+25= 39. If we know that the mathematical equation of positive+negative= negative, then we switch the 39 to -39.
11/3 = 3 2/3 as a mixed fraction or proprr fraction

Answer:
107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
Step-by-step explanation:
Since a label prints in the pediatric pharmacy satellite for 500 mL of dextrose 15% solution, but this concentration is not available commercially and needs to be compounded, and available in your pharmacy, you have a 1 L bag of sterile water and a 1 L bag of dextrose 70% available to compound the solution, to determine how many mLs of each are needed to make the requested solution, the following calculation must be performed:
500 x 0.15 = 75
100 x 0.70 = 70
A x 0.70 = 75
A = 75 / 0.70
A = 107.14
Therefore, 107.14 ml of 70% dextrose and 392.86 ml of sterile water should be used.
Fencing a garden would be Perimeter because your trying to find how much fencing you would need so you can surround the garden.
The area of the garden is how much space there is. Ex. 5ft×9.5ft=47.5ft² . The 5ft would be the length of the garden, and the 9.5ft would be the width. But to find area, you would need to do L×W, or 5ft×9.5ft in this case for area.
But to find Perimeter, you need to do L+L+W+W. If we use the numbers from before for the area example, you would be doing 5ft+5ft+9.5ft+9.5ft, you would be getting 29ft.
If you want the definitions to better understand this, here they are:
Perimeter: the total distance around the edge of the figure.
Area: the number of unit squares that can be contained within it.(hence the reason "²" was at the end of the total in the example for area I provided.)
