Think about it…. Discussion: What is the decimal expansion in Ex. 1? Did you use long division? Why or why not? What is the decimal expansion in Ex. 2? Did you use long division? Why or why not? What is the decimal expansion in Ex. 3? Did you use long division? Why or why not? What is the decimal expansion in Ex. 4? Did you use long division? Why or why not? How did you know when to stop? Remember, when something is divisible by prime factorization of 2s and 5s, the decimal expansion is FINITE.
