So, I subtracted 7/9 - (-13/18) and got an answer of 1/18. Would this answer be negative or positive????

positive

BTW, the answer in not 1/18

7/9 - (-13/18)=
= 14/18 + 13/18
= 27/18
= 3/2 or 1 1/2

To determine whether the answer is negative or positive, we need to understand the rules of subtracting fractions. When subtracting fractions, we change the operation to addition and take the opposite of the second fraction. In this case, we have 7/9 - (-13/18).

To take the opposite of a fraction, we simply change its sign. The opposite of -13/18 is 13/18.

So, our expression becomes 7/9 + 13/18.

To add fractions, we need a common denominator. In this case, the least common multiple of 9 and 18 is 18. We can rewrite 7/9 as 14/18 by multiplying the numerator and denominator by 2: (7/9) * (2/2) = 14/18.

Now our expression is 14/18 + 13/18. When the denominators are the same, we can add the numerators and keep the common denominator. So, (14 + 13)/18 = 27/18.

The answer is 27/18. However, we can simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 9. Dividing 27 by 9 and 18 by 9, we get 3/2.

So, the simplified answer is 3/2, which means the answer is positive since both the numerator and denominator are positive.
