Without actually performing the long division, state whether the following rational numbers will have a terminating decimal expansion or a non-terminating repeating decimal expansion: (i)13/3125 (ii)17/8 (iii)64/455 (iv)15/1600 (v)29/343 (vi)23/2³*5² (vii)129/2²* 57* 75 (viii)6/15 (ix)35/50 (x)77/210, Question 2. Write down the decimal expansions of those rational numbers in Question 1 above which have terminating decimal expansions. (i)13/3125 = 0.009375 (ii)17/8 (iii)64/455 none- terminating (iv)15/1600 (v)29/343 it is none – terminating (vi)23/2³*5² = 23/200 (vii)129/2²* 57*75 it is none terminating (viii) 6/15 = 2/5 = 0.4 (ix)35/50, Question 3. The following real numbers have decimal expansions as given below. In each case, decide whether they are rational or not. If they are rational, and of the form p , q you say about the prime factors of q?.
