Question

Find the LCM of the fractions 5/8, 3/4, 1/2
1. 15
2. 40
3. 15/2
4. 15/8

Answer 1

Correct Answer - Option 3 : 15/2

Given:

The fractions are 5/8, 3/4 and 1/2

Concept used:

LCM of the fraction = LCM of numerator/HCF of 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 = 15/2 

∴ The LCM of the fraction is 15/2.
