hcf=1 and lcm = 1/10
ReplyDeleteLCM and HCF of 0.5 and 0.2
ReplyDeleteHCF = 0.1 = 1/10
LCM = 1
check : HCF = p*q/LCM
=> 0.1 = 0.5*0.2/1
=> o.1 = 0.1/1
so, LHS = RHS
HCF of the fractions = HCF of numerators / LCM of denominators
Delete==> 1/10
LCM of the fractions = LCM of numerators / HCF of numerators
==> 1/1 = 1
HCF = 1/10
LCM = 1
LCM = 1
ReplyDeleteHCF= 0.1 or 1/10
HCF is 1.
ReplyDeleteLCM is 0.1
HCF=1/10
ReplyDeleteLCM=1
HCF = 1
ReplyDeleteLCM = 1/10
The LCM of two or more fractions is the least fraction or integer which is exactly divisible by each of them.
ReplyDeleteLCM of the fractions = LCM of numerators / HCF of denominators
Question : 1/2 & 1/5
Answer : 1/1 = 1
The HCF of two or more fractions is the highest fraction which is exactly divisible by each of the fractions.
ReplyDeleteHCF of the fractions = HCF of numerators / LCM of denominators
Question :HCF of 1/2 & 1/5
Answer : HCF = 1/10 = 0.1
