a. Which fractions a/b have terminating decimals?
b. Which fractions a/b have repeating decimals?
c. Sometimes (for example 1/12 ) only part of the decimal repeats while in other cases (for example 1/7 ) the whole decimal repeats. Assuming a/b is a reduced fraction, how can you tell which of these two scenarios will occur? Explain.
*d.* Marcus says he computed and found
0.0588235294
Josie looks at this answer for a second or two and tells Marcus that he is mistaken. Josie did NOT calculate any of the numbers in this decimal. How might Josie have known Marcus calculation is incorrect?
