In this question the main part is to convert the mixed fraction into the decimal form. I hope the procedure i am going to show would be the easiest procedure to solve this kind of problems. Now let us get down to solving the problem in hand. 6 3/4 = 27/4 We have reached the above deduction by multiplying 6 and 4 and then adding 3 with the result. Now we will come down to the decimal part. 27/4 = 6.75 So 6.75 is the decimal form of 6 3/4.
