Answer 1

Let x=4.2030303....----(1)
Multiply (1) with 10
10x=42.030303.....---'(2)
Multiply (2) with 100
1000x=4203.030303...-----(3)
Subtract (2) from (3)
990x =4161
x=4161/990
x=1387/330

Answer 2

Hi there !!

x = 4.2030303 ......

10 x = 42.0303..... ---> (1)

1000 x = 4203.030303.... --->(2)


Subtracting 1) from 2)

1000 x - 10x = 4203 - 42

990x = 4161

x = 4161/990
