Do you mean, which answers contain pairs of numbers that are equal?
A) 1 5/7 = 7/7 + 5/7 = 12/7. This is not the same as 6/7.
B) 3/2 and 2/3 are not equal.
C) 10/12 = (2*5)/(2*6) = 5/6, so C is correct.
D) 3 1/2 = 3*(2/2) + 1/2 = 6/2 + 1/2 = 7/2
4 3/4 = 4*(4/4) + 3/4 = 16/4 + 3/4 = 19/4. These are not equal.

Do you mean like as in "same denominator"? If that's the case than your right, answer A is correct.

If you mean which of these pairs contain fractions which are equal it is C. Since:

$<br /> \frac{10}{12}=\frac{2\times 5}{2 \times 6}=\frac{2}{2}\times \frac{5}{6}=\frac{5}{6}<br />$

If the "same denominator" thing is correct, then both answers A and C are technically correct, since 10/12 = 5/6 has the same denominator as 5/6.
