a. Separate the fractions; 2/6, 2/5, 6/13, 1/25, 7/8, and 9/29 into two categories; those that can be written as a terminating decimal and those that cannot. Write an explanation of how you made your decision. b. orm a conjecture about which ractions can be expressed as terminating decimals. c. test your conjecture on the following fractions, 6/12, 7/15, 28/140, and 0/7. d. use the idea of equivalent fractions and common multiples to verify your conjecture.

By dividing>>
2/6 = 0.333333
2/5 = 0.40
6/13 = ?
1/25 = ?
7/8 = ?
9/29 = ?
If you get stuck on the rest of this assignment, please repost and explain what stumps you. 
I got part a. I do not understand the rest. b. form a conjecture about which fractions can be expressed as terminating decimals. c. test your conjecture on the following fractions; 6/12, 7/15, 28/140, and 0/7. d. use the idea of equivalent fractions and common multiples to verify your conjecture.

b. What do think the fractions that are expressed as terminating decimals have in common? Think about equivalent fractions and common multiples.
c. Do these fractions follow the same pattern as what you decided about the first set of fractions?
d. Why or why not?
Note: The most important part of this assignment is what you think. The right answer is not as important as how you analyze this problem.
