Answer:

If what I think youre saying is correct, then it should be 1/9

Step-by-step explanation:

4/15 + (-7/45)

Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.

12/45 + (-7/45)

As the fraction on the right side is negative, it is taken away from the left fraction, hence:

(12 - 7)/45

Therefore, with simple subtraction,

5/45

Simplify to 1/9
