To subtract fractions, we need to have a common denominator. In this case, both fractions already have a common denominator of 15.
So, we can subtract the numerators directly:
2/15 - (-5/15) = 2/15 + 5/15
Adding the numerators:
= (2 + 5)/15
Simplifying the numerator:
= 7/15
Therefore, 2/15 minus -5/15 is equal to 7/15.
