Find a common denominator for all fractions.

Step 1: Find a common denominator for all fractions. The given fractions are $\frac{1}{3}, \frac{1}{2}, \frac{1}{4}, \frac{1}{5}$. The denominators are 3, 2, 4, and 5. The least common multiple (LCM) of 2, 3, 4, and 5 is 60. Step 2: Convert each fraction to an equivalent fraction with a denominator of 60. $$\frac{1}{3} = \frac{1 \times 20}{3 \times 20} = \frac{20}{60}$$ $$\frac{1}{2} = \frac{1 \times 30}{2 \times 30} = \frac{30}{60}$$ $$\frac{1}{4} = \frac{1 \times 15}{4 \times 15} = \frac{15}{60}$$ $$\frac{1}{5} = \frac{1 \times 12}{5 \times 12} = \frac{12}{60}$$ Step 3: Arrange the fractions in ascending order by comparing their numerators. The numerators are 20, 30, 15, 12. Arranging them in ascending order: 12, 15, 20, 30. So, the fractions in ascending order are: $$\frac{12}{60}, \frac{15}{60}, \frac{20}{60}, \frac{30}{60}$$ Step 4: Write the original fractions in the determined order. $$\frac{1}{5}, \frac{1}{4}, \frac{1}{3}, \frac{1}{2}$$ $$\boxed{\frac{1}{5}, \frac{1}{4}, \frac{1}{3}, \frac{1}{2}}$$ 3 done, 2 left today.
