Answer:
Explanation:
Convert both fractions to have the same lowest common denominator (LCD) so we can subtract.
We should list multiples of 3 & 9 to find that number.
3: 3, 6, 9
9: 9, 18, 27
Our LCD is 9.
To convert -2/3 to have a denominator of 9, we must multiply by 3/3 (whatever you do to denominator you must do to numerator & vice versa).
We get that:
5/9 already has a denominator of 9 so we leave it alone.
Then we subtract the numerators to get our answer:
