Answer: 380 / 99

Explanation:

1) Given decimal number: 3.8383...

2) Call the fraction x

x = 3.8383...

3) Multiply both sides by 100

100x = 383.8383...

4) Subtract the first expression from the second one:

100x - x = (383.8383...) - (3.8383...)

99x = 383 - 3

99x = 380

x = 380 / 99

3) You can check the result dividing 380 ÷ 99, which is 3.8383...
