Answer:
the first one
Explanation:
Here's how to subtract 2/6 from 5/9:
5
9
−
2
6
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 5 by 6, and get 30.
Then we multiply 2 by 9, and get 18.
Next we give both terms new denominators -- 9 × 6 = 54.
So now our fractions look like this:
30
54
−
18
54
Step 2
Since our denominators match, we can subtract the numerators.
30 − 18 = 12
So the answer is:
12
54
