Question

2:-

decimal expansion each has:
(i)36/100
(ii) 33/8
(iii)2/9
(iv)2/11
(v)3/13
(vi)329/400

3:-
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)23/75
(iv)6/15
(v)1258/625
(vi)77/210.

Answer 1

Answer:

2..

36/100=0.36 it is a terminating decimal.

33/8=4.125 it is a terminating decimal.

2/9=0.222222......... it is a recurring decimal..and non terminating decimal

2/11=0.18181818.....it is a repeating decimal.

3/13=0.2307692308..it is a non terminating decimal.

329/400=0.8225 it is a terminating decimal...

3..

see the trick here is if we can able to write denominator number in the form of multiples of 2 or 5 or both it is a terminating decimal... or if we can write denominator number in the form of multiplying with 2 and 5 by getting multiples of 10 I denominator also a terminating decimal...

13/3125=by multiplying both numbers with 32 we get 416/100000 so then the answer is 0.0000k 416..

Hope u understand
