Answer: The number line is attached.
1. You have the following fractions given in the problem above:
[tex]\frac{1}{2},\frac{1}{4},\frac{1}{5},\frac{1}{3}[/tex]
2. You can write them in decimal form by dividing the numerator and the denominator. Keeping this on mind, you have:
[tex]\frac{1}{2}=0.5[/tex]
[tex]\frac{1}{4}=0.25[/tex]
[tex]\frac{1}{5}=0.2[/tex]
[tex]\frac{1}{3}=0.33[/tex]
3. Now, you can put these positive numbers in the number line, as you can see in the figure attached.
