What is the LCM of 147/64 and 30/44 ?

A. 735/704

B. 3/704

C. 735/2

D. 3/735

Answer : C. 735/2


Explanation:


    Find the LCM of the Numerators.
    LCM (147, 30) = 1470
    Find the HCF of Denominators.
    HCF (64, 44) = 4
    So, the LCM of 147/64 and 30/44 is (LCM of Numerators) / (HCF of Denominators) = 1470 / 4 = 735/2
