0.3454545…..=_____________
A. 345/1000
B. 350/995
C. 355/900
D. 342/990
I got this question in exam.
My question is based upon Real Numbers and their Decimal Expansions topic in section Number Systems of Mathematics – Class 9
Right answer is D. 342/990
To explain I would say: Let 0.3454545…=x
Then, 100x=34.54545…..
100x=34.2 + 0.3454545…
100x=34.2 + x
99x=34.2
Then, x=34.2/99
x=342/990.
