Answer:

  7 2/3

Step-by-step explanation:

The even number of minus signs cancel, so the problem is an addition problem.

  5 2/5 +2 4/15

The fractions can be added only when they have a common denominator. 15 works for that purpose.

  5 6/15 +2 4/15 = (5 +2) +(6/15 +4/15) = 7 10/15

The fraction 10/15 can be reduced by removing a common factor of 5 from numerator and denominator.

 = 7 2/3
