Answer:
34/99 - 2/10 - 2/3
Step-by-step explanation:
0.34
Let x = 0.343434..... --------1
multiplying 100 on both sides
2---- 100x = 34.343434...
1 ----- x = 0.343434... subtracting 1 from 2
99x= 34.000...
x= 34/99
=> 0.34bar = 34/99
0.6
Let y= 0.666...--------3
multiplying 10 on both sides
=> 10y=6.666...--------4
y= 0.666...--------3 subtracting 3 from 4
9y=6.000...
y=6/9
=2/3
=> 0.34 bar - 0.2 + 0.6 bar
= 34/99 - 2/10 - 2/3.
in the first one why u have directly multiply by 100 not 10
in the second one u hadn't subtracted
also in first one the bar is on the 4 only that is why u have to multiply it by 10 two times
