Answer: No
Step-by-step explanation: In order to write 7/9 in lowest terms, we divide the numerator and denominator by the greatest common factor of 7 and 9.
Since the factors of 7 are 1 and 7 and the factors of 9 are 1, 3, and 9 the greatest common factor of 7 and 9 is 1.
This means that we divide the numerator and denominator by 1.
7 ÷ 1 ≈ 7
9 ÷ 1 ≈ 9
Therefore, 7/9 is already written in lowest terms.
