Because 3 2/4 would be the answer when you subtract it and most teachers and/or tests want you to simplify the answer which would be 1/2 because you would divide the numerator and denominator by 2.
what formula is applied, I mean what method
D. 4.25 < 43/10 < 13/3
4.25 = 4.25
43/10 = 4.3
13/3 = 4.33
4.25 < 4.3 < 4.33
Answer:
9r
