Write two numbers whose decimal expansions are terminating.

Without actually performing the long division, state whether the following rational numbers will have terminating decimal expansion or a non-terminating repeating decimal expansion. Also,find the number of places of decimals after which the decimal expansion terminates.(17)/(8) (ii) (64)/(455) (iii) (29)/(343)

Without actually performing the long division, state whether the following rational numbers will have terminating decimal expansion or a non-terminating repeating decimal expansion. Also,find the number of places of decimals after which the decimal expansion terminates.(15)/(600) (ii) (13)/(3125) (iii) (23)/(2^(3)5^(2))

Let x = 7/(20 xx25) be a rational number . Then x has decimal expansion which terminates :
