Option(C) 3/10 is the correct answer.
Given,
The total hours required for homework = 5 hours
A student has done hours of homework = 3 and half hours
To Find,
The part of his homework is yet to be done =?
Solution,
The total hours required for homework = 5 hours
A student has done hours of homework = 3.5 hours
The part of homework done by student = 3.5 / 5
The part of homework done by student = 35 / 50 = 7 / 10
The part of his homework that is yet to be done = 1 - Part of homework done
The part of his homework that is yet to be done = 1 - 7 / 10
The part of his homework that is yet to be done = (10 - 7)/10
The part of his homework that is yet to be done = 3 / 10
Hence, 3/10 part of his homework is yet to be done.
