Express the follo

Answer :

i. 0.3


=


ii.


Let x = = 0.47474747… ..(i)


Multiplying equation (i) with 100. We get,


100x = 47.4747474.. ..(ii)


Subtracting (ii) for (i) i.e. (ii) – (i). We get,


99x = 47


x =


Thus,


iii.


Let x = = 1.27272727… ..(i)


Multiplying equation (i) with 100. We get,


100x = 127.27272727.. ..(ii)


Subtracting (ii) for (i) i.e. (ii) – (i). We get,


99x = 126


x =


Thus,


iv.


Let x = = 1.2353535… ..(i)


Multiplying equation (i) with 10. We get,


10x = 12.353535.. ..(ii)


Multiplying equation (i) with 1000. We get,


1000x = 1235.3535.. ..(iii)


Subtracting (iii) for (ii) i.e. (iii) – (ii). We get,


990x = 1223


x =


Thus,
