Let's look at the denominator and multiply it by 8. If the numerator is less than the product, then that is the answer. You could also just divide since every fraction is basically division.
Let's look at each option.
║First Option║
8×3=24
17<24
Let's divide.
5 2/3
So, that is the answer.
Let's look at why the others are not.
For the second option, when you divide, it is 9 1/3.
The third option, when you divide, it is 9.25.
The fourth option, when you divide, it is 10.5.
So, the first option is less than 8.
