Juan’s three math quizzes this week took him 1/3 hour, 4/6 hour, and 1/5 hour to complete. List the lengths of time in order from least to greatest.

Rewrite the fractions to have a common denominator:

1/3 = 10/30

4/6 = 20/30

1/5 = 6/30

Now compare the numerators and list from smallest to largest:

6/30, 10/30, 20/30

The order would be:

1/5, 1/3, 4/6

a² + b²= c²

24² + 7² = c²

c= 25
