Mark \((\checkmark)\) against the correct answer in the following: Which is smaller between \(\frac{-5}{6}\) and \(\frac{-7}{12}?\)
1 \(\frac{-5}{6}\)
2 \(\frac{-7}{12}\)
3 \(\frac{6}{5}\)
4 Cannot be compared.
Explanation:
\(\frac{-5}{6}\) Since LCM of 6 and 12 is 12 \(\frac{-5\times2}{6\times}=\frac{-10}{12}\) \(\frac{-7\times1}{12\times1}=\frac{-7}{12}\) \(\frac{-5}{6}<\frac{-7}{12}\)

What is the additive identity element in the set of whole numbers?
1 0
2 1
3 -1
4 None of these.
Explanation:
0 If a is a whole number then a + 0 = a = 0 + a. Therefore, 0 is the additive identity element for addition of whole number because it does not change the identity or value of the whole number during the operation of addition. Hence, the correct answer is option (a).

For any two rational numbers x and y, which of the following properties are correct (i) x < y (ii) x = y (iii) x > y?
1 Only (i) and (ii) are correct
2 Only (ii) and (iii) are correct
3 Only (ii) is correct
