To subtract these two numbers, I will convert them into decimal form to make it much easier.
16 1/8 = 16.125
5 3/4 = 5.75.
Now that we have them in decimal form, we can subtract!
16.125 - 5.75 = 10.375
10.375 put into fraction form is 10 3/8.
A.) Matches 10 3/8, so A is your answer.
I hope this helps!
