The correct answers are choices A and C.
The reason is that both of these chose has a positive 1/3 and a negative 2/5 being combined.
1/3 - 2/5 = 1/3 + (-2/5)
A. 1/3+(-2/5)
C. |1/3|-|2/5|; these are absolute value(distance from zero), so it would be the exact same as the original problem after the absolute value is applied.
