Solution:
Given that At a golf course there are 18 holes
Therefore,
Total number of holes = 18
Of the 18 holes 3 are par threes 8 are par fours and 7 are par fives
So there are par 3, par 4 and par 5
Number of par 3 holes = 3
Number of par 4 holes = 8
Number of par 5 holes = 7
To find: fraction of the holes that are par threes Par fives and par fours
Find the fraction of par 3 holes:
![\text{ fraction of par 3 holes} = \frac{\text{ number of par 3 holes}}{\text{ total number of holes }}](https://img.qammunity.org/2021/formulas/mathematics/high-school/inu8fqis7ezv55w0z7netim99feb8oqfy7.png)
![\text{ fraction of par 3 holes} = (3)/(18) = (1)/(6)](https://img.qammunity.org/2021/formulas/mathematics/high-school/mg7d5g33870ec6l55h360uuea1tdvhzm8m.png)
Find the fraction of par 4 holes:
![\text{ fraction of par 4 holes} = \frac{\text{ number of par 4 holes}}{\text{ total number of holes }}](https://img.qammunity.org/2021/formulas/mathematics/high-school/4dxg7323f07a06083yy85uvbrzffes0yoy.png)
![\text{ fraction of par 4 holes} = (8)/(18) = (4)/(9)](https://img.qammunity.org/2021/formulas/mathematics/high-school/i74fjsda0vaqe8o4qnw1opumk2j5d4no1c.png)
Find the fraction of par 5 holes:
![\text{ fraction of par 5 holes} = \frac{\text{ number of par 5 holes}}{\text{ total number of holes }}](https://img.qammunity.org/2021/formulas/mathematics/high-school/h47mkqlsirup12em35nnpbnt8oy8zf7qy8.png)
![\text{ fraction of par 5 holes} = (7)/(18)](https://img.qammunity.org/2021/formulas/mathematics/high-school/tp9rbn0vo9gl0vin3kqv4yr1cuzfih6wq7.png)
Thus the required fractions are found
