(2/3) + (1/6) =
First get the LCD (Least Common Denominator).
3 is prime.
6
3 * 2 = 6
1 is prime
3 is prime
2 is prime
1 * 3 * 2 = 6
LCD = 6
The LCD is the new denominator.
Divide the LCD by the original denominator then multiply with the numerator.
(1/6)
6 / 6 = 1
1 * 1 = 1
The first fraction is (1/6).
(2/3)
6 / 3 = 2
2 * 2 = 4
The second fraction is (4/6).
The problem is now.
(1/6) + (4/6) =
Add the numerators.
1 + 4 = 5
The final answer is (5/6)
