Question

plz help me do full solution

Answer 1

1) let x=0.99999               -1
multiply both sides by 10
10x=9.99999                -2
by 1 from 2 we get
9x=9
x=9/9
x=9 

2)letx= 0.373737      -1
multiply both sides by 100 we get
100x=37.373737      -2
by subtracting 1 from 2 we get
99x=37
x=37/99

3)let x= 0.5434343      -1
mutiply both sides by 100
100x=54.3434343     -2
2-1
99x=53.8
x=53.8/99
x=538/990

4)letx=6.3333      -1
multiply both sides by 10
10x=63.3333      -2
2-1
9x=57
x=57/9

5)let x=3.121212      -1
multiply both sides by 100
100x=312.121212      -2
99x=309
x=309/99
