-6%2F5-13%2F5%2B4%2F5 Start with the given expression


Since every denominator is equal to one another, we can combine the fractions.

%28-6-13%2B4%29%2F5 Combine the fractions by adding/subtracting every numerator over the same denominator


%28-19%2B4%29%2F5 Subtract 13 from -6 to get -19. In other words, -6-13=-19 (note: this is where you made the mistake)


%28-15%29%2F5 Add 4 to -19 to get -15. In other words, -19%2B4=-15


-3 Reduce %28-15%29%2F5 to get -3



So -6%2F5-13%2F5%2B4%2F5 simplifies to -3. In other words, -6%2F5-13%2F5%2B4%2F5=-3
