A) \[\frac{3}{4}>-2>\frac{-11}{20}>\frac{4}{-5}\]
B) \[\frac{3}{4}>\frac{-11}{20}>\frac{-4}{5}>-2\]
C) \[\frac{3}{4}>\frac{4}{-5}>-2>\frac{-11}{20}\]
D) \[\frac{3}{4}>\frac{4}{-5}>\frac{-11}{20}>-2\]
Correct Answer: B
Solution :
L.C.M. of 5, 4 and 20 is 20. \[\frac{4}{-5}\times \frac{4}{4}=\frac{16}{-20};\frac{3}{4}=\frac{3\times 5}{4\times 5}=\frac{15}{20}\] \[-2<\frac{4}{-5}<\frac{-11}{20}<\frac{3}{4}\] or \[\frac{3}{4}>\frac{-11}{20}>\frac{4}{-5}>-2\]is the required descending order. Rewrite equivalent fractions of the given fractions and then compare then. Arrange them in descending order.
