Mark \((\checkmark)\) against the correct answer in the following: The product of two numbers is \(\frac{-1}{6}\) If one of them is \(\frac{-5}{8}\) the other number is:
1 \(\frac{-4}{15}\)
2 \(\frac{4}{15}\)
3 \(\frac{15}{4}\)
4 \(\frac{-15}{4}\)
Explanation:
\(\frac{4}{15}\) Let the other number to be x \(\frac{-5}{8}\times\text{x}=\frac{-1}{6}\) \(\Rightarrow\text{x}=\frac{-1}{6}\div\Big(\frac{-5}{8}\Big)\) \(=\frac{-1}{6}\times\Big(\frac{8}{-5}\Big)\) \(=\frac{-4}{-15}\) \(=\frac{4}{15}\)

1 \(1\frac{1}{21}\)
2 \(-1\frac{1}{21}\)
3 \(\frac{5}{21}\)
4 \(\frac{-5}{21}\)
Explanation:
\(-1\frac{1}{21}\) The correct option is (b). \(\frac{2}{3}-1\frac{5}{7}\) \(\frac{2}{3}\frac{12}{7}\) LCM of 3 and 7 is 21 \(=\frac{14-36}{21}\) \(=\frac{-22}{21}\) \(=-1\frac{1}{21}\)
