Actually, the bot is right, but you didn't make those numbers into a fraction like this: 2/5 + (- 1/3)
Apologies for the oversight. You're correct, the expression "2/5 + (-1/3)" can be simplified by converting the numbers to fractions first:
To add fractions, we need the same denominator. The least common multiple of 5 and 3 is 15. So, we will convert both fractions to have denominators of 15.
2/5 = (2/5) * (3/3) = 6/15
-1/3 = (-1/3) * (5/5) = -5/15
Now, we can add the fractions:
6/15 + (-5/15) = (6 - 5)/15 = 1/15
Therefore, the simplified result of 2/5 + (-1/3) is 1/15.
