Answer 1

1)Let,

x = 0.42

100x = 42

x = 42/100

2)Let,

x = 0.5 recurring

10x = 5.5 recurring

9x = 5

x = 5/9

3)Let,

x = 35.345 recurring

1000x = 35345.345 recurring

999x = 35310

x = 35310/999

4)Let,

x = 0.38 5 recurring

100x = 38.5 recurring

1000x = 385.5 recurring

900x = 347

x = 347/900
