I think the answer is C hope this would help you
The first thing that fraction can can represent is Pizza, pie,and onions. Because you can cut the pizza, the pie, and the onion into different or equal spaces. Hoped it helped.
First, convert your mixed numbers into improper fractions, so 8+3/8=69/8 and 2+1/3=7/3. Now you have 69/8=r-(7/3). Now, add 7/3 to both sides, so (69/8)+(7/3)=r. Now, just add your fractions, so (69/8)+(7/3)=207/24+56/24=(207+56)/24=263/24. If you need to, this can be converted back into the mixed number 10+23/24.
f(x)=x-4f(3)=3-4so f(3)= -1
