Question

find the LCM of 1, 5/3, 5/2

Answer 1

Let us assume two fractions (a/b) and (c/d).

To find LCM and HCF of (a/b) and (c/d) the generalized formula will be:

H.C.F = H.C.F of numerators / L.C.M of denominators

L.C.M = L.C.M of numerators / H.C.F of denominators.

So for finding LCM(1,5/3,5/2) we need to find LCM(1,5,5) and HCF(1,3,2).

1)LCM(1,5,5)=5

2) HCF(1,3,2)=1

So LCM(1,5/3,5/2)=LCM (1,5,5)/HCF(1,3,2)

LCM (1,5/3,5/2)=5/1=5.
