Answer :
The correct answer is:
5/6.
Explanation:
To simplify this fraction, we divide the numerator and denominator by the greatest common factor.
The factors of 10 are: 1, 2, 5 and 10.
The factors of 12 are: 1, 2, 3, 4, 6, and 12.
The greatest common factor of the two is 2.
Simplifying this, we have:
10/12 = (10÷2)/(12÷2) = 5/6.
