Answers

Answered by Ronnie86

first find the LCM of the denominator that is 1 and 2.
the LCM is 2.

Ronnie86: the numerator is 6 actually the fraction is 6 upon 1 therefore if we have multiplied 1 we do in the denominator then we will multiply 6 with also 2 therefore the fraction will become 12 upon 2

mathskakeeda: ans given 126 .. we normally do in case of lcm -lcm of numer/hcf of denomimator

Ronnie86: what is 126 the sum of the difference of the product

mathskakeeda: didnt get u

mathskakeeda: i thnk ans 126 is wrong

Ronnie86: yes it can be

mathskakeeda: hm

Ronnie86: is 126, the sum, the difference or the product

mathskakeeda: only given as the ans of lcm of 6 and 21/2

mathskakeeda: nothing else mentioned

Answer:

The L.C.M. of 6 and 21/2 is 42.

Step-by-step explanation:

The given numbers are 6 and $\frac{21}{2}$ .

The LCM of $\frac{a}{b}$ and $\frac{c}{d}$ is

$L.C.M(\frac{a}{b},\frac{c}{d})=\frac{L.C.M.(a,c)}{H.C.F.(b,d)}$

$L.C.M(\frac{6}{1},\frac{21}{2})=\frac{L.C.M.(6,21)}{H.C.F.(1,2)}$

$L.C.M(\frac{6}{1},\frac{21}{2})=\frac{42}{1}$

$L.C.M(\frac{6}{1},\frac{21}{2})=42$

Therefore the L.C.M. of 6 and 21/2 is 42.
