To solve the problem of ordering fractions in increasing order, we need to compare each set of fractions and arrange them from smallest to largest. Here's how we can approach each set step by step:

---

General Steps:

1. Find a Common Denominator: Convert all fractions in a set to have the same denominator so they can be easily compared.
2. Compare Numerators: Once the denominators are the same, compare the numerators to determine the order.
3. Write the Fractions in Order: Arrange the fractions from smallest to largest based on the comparison.
