Answer:
50 pockets
Step-by-step explanation:
Given
![Total = 75\ yd](https://tex.z-dn.net/?f=Total%20%3D%2075%5C%20yd)
![Pocket = 1\frac{1}{2}yd](https://tex.z-dn.net/?f=Pocket%20%3D%201%5Cfrac%7B1%7D%7B2%7Dyd)
Required
Determine the number of pockets
To calculate the required , we make use of:
![Pockets = \frac{75yd}{1\frac{1}{2}yd}}](https://tex.z-dn.net/?f=Pockets%20%3D%20%5Cfrac%7B75yd%7D%7B1%5Cfrac%7B1%7D%7B2%7Dyd%7D%7D)
![Pockets = \frac{75}{1\frac{1}{2}}}](https://tex.z-dn.net/?f=Pockets%20%3D%20%5Cfrac%7B75%7D%7B1%5Cfrac%7B1%7D%7B2%7D%7D%7D)
Convert the denominator to decimal
![Pockets = \frac{75}{1.5}](https://tex.z-dn.net/?f=Pockets%20%3D%20%5Cfrac%7B75%7D%7B1.5%7D)
![Pockets = 50](https://tex.z-dn.net/?f=Pockets%20%3D%2050)
