13/18 + 11/18 then write all answers in the lowest terms?
A-8/9?
27/18 now divide each by 9, numerator and denominator.
To add fractions, you need to have a common denominator. In this case, the denominators are already the same, so you can simply add the numerators.
Therefore, 13/18 + 11/18 = 24/18.
To write the answer in the lowest terms, divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 24 and 18 is 6.
Dividing both the numerator and denominator by 6, we get:
24 ÷ 6 / 18 ÷ 6 = 4/3.
So, the answer in the lowest terms is 4/3, and it is not equal to -8/9.
