Detailed Solution

Given decimal 0.35  .
If there is 0   towards the left of the decimal, then it will be a proper fraction.
So, 0.35 is a proper fraction.
Find the place value of numbers present towards the right of the decimal 0.35  .
3   is in 110th place and 5   is in 1100th place.
There are 2   places to the right of the decimal point.
So multiply the numerator and denominator with 100  .
We get,
0.35100 100 = 35 100  
By simplification,
35 100 = 7 20  
The fraction is 7 20  .
Hence, option 1) is correct.
