Answer 1

To subtract 9 7/10 - 6 1/4, let's convert both mixed numbers to improper fractions.

9 7/10 can be written as (9*10 + 7)/10 = 97/10
6 1/4 can be written as (6*4 + 1)/4 = 25/4

Now we can subtract the fractions:

97/10 - 25/4 = (97*4 - 25*10)/(10*4) = (388 - 250)/40 = 138/40 = 69/20

Therefore, the difference is 69/20 or 3 9/20.

So, the correct answer is: Start Fraction 3 over 20 End Fraction
