Question

Without actual division, check which of the following rational numbers can be expressed as non-terminating repeating decimals : 4/9 b 27/4 c 6/15 d 5/18 e 6/28 f 11/50.​

Answer 1

Answer:

x is a rational number whose simplest form is pq, where p and q are integers and q≠0. Then, (i) x is terminating only when q is of the form (2m×5n) for some non-negative integers m and n. (ii) x is non-terminating and repeating, if q≠(2m×5n).
