Answer:
B. 4/9
Explanation:
We can simplify the given expression by finding a common denominator for 18 and 12. The least common multiple of 18 and 12 is 36.
Multiplying the first fraction 5/18 by 2/2 (which equals 1) to get a denominator of 36:
5/18 = 5/18 x 2/2 = 10/36
Multiplying the second fraction 2/12 by 3/3 (which equals 1) to get a denominator of 36:
2/12 = 2/12 x 3/3 = 6/36
Now we can add the two fractions with the same denominator:
10/36 + 6/36 = 16/36
We can simplify this fraction by dividing the numerator and denominator by their greatest common factor, which is 4:
16/36 = 4/9
Therefore, the solution is B) 4/9.
