Haryana Police Constable Model Paper 3

Given:
The fractions are $\frac{5}{8},\frac{3}{4}\mathrm{and}\frac{1}{2}$
Concept used:
LCM of the fraction $=\frac{\mathrm{LCM}\mathrm{of}\mathrm{numerator}}{\mathrm{HCF}\mathrm{of}\mathrm{denominator}}$
Calculation:
LCM of numerators = LCM of (5, 3 , 1)
LCM (5, 4, 1) = 5 × 3 × 1 = 15
HCF of denominators = HCF of ( 8, 4, 2)
HCF (8, 4 ,2) = 2
LCM of fraction = $\frac{15}{2}$
∴ The LCM of the fraction is $\frac{15}{2}$ .
