Answer: {x|x is a natural number between 16 and 21}.
Step-by-step explanation:
Here we can see the natural numbers are: <u>17, 18, 19, 20</u>
We can say these numbers are in between 16 to 21
Therefore, the set is {x|x is a natural number between 16 and 21}
The smaller denominator will give a larger fraction. Another method for comparing is to think of the fractions. In this example it is obvious that 1/3 is smaller than 7/8. For one thing, 1/3 is smaller than 1/2 and 7/8 is larger than 1/2.
