A) \[\frac{1}{54}\]
B) \[\frac{10}{27}\]
C) \[\frac{20}{3}\]
D) \[\frac{3}{20}\]
Correct Answer: C
Solution :
| [c] We know that, LCM of fractions \[=\frac{\text{LCM of numerators}}{\text{HCF of denominators}}\] \[\therefore \] Required LCM \[=\frac{\text{LCM}\,\,\text{of}\,\,\text{1,}\,\,\text{2,}\,\,\text{5}\,\,\text{and}\,\,\text{4}}{\text{HCF}\,\,\text{of}\,\,\text{3,}\,\,\text{9,}\,\text{6}\,\,\text{and}\,\,\text{27}}\text{=}\frac{\text{20}}{\text{3}}\] |
