A) 3/8, 1/2, 4/5
B) 1/2, 4/5, 3/8
C) 4/5, 1/2, 3/8
D) 3/8, 4/5, 1/2
Correct Answer: A
Solution :
Given fractions are \[\frac{1}{2},\frac{4}{5},\frac{3}{8}\] L.C.M. of 2, 5, 8 = 40 \[\therefore \] \[\frac{1}{2}\times \frac{20}{20}=\frac{20}{40},\frac{4}{5}\times \frac{8}{8}=\frac{32}{40},\frac{3}{8}\times \frac{5}{5}=\frac{15}{40}\] So, order from the smallest to biggest is \[\frac{15}{40},\frac{20}{40},\frac{32}{40}\] i.e., \[\frac{3}{8},\frac{1}{2},\frac{4}{5}.\]
