Question

write down the decimal expansion of those rational numbers in question 1 above which have terminating decimal expansion​

Answer 1

Answer:

The terminating decimal expansion means that the decimal representation or expansion terminates after a certain number of digits. A rational number is terminating if it can be expressed in the form: p / q where q is of the form 2n × 5m.

The rational numbers 13/3125, 17/8, 15/1600, 23/2352, 6/15, and 35/50 have a terminating decimal expansion whereas, 64/455, 29/343, 129/225775, and 77/210 have a non-terminating repeating decimal expansion.
