Answer 2

Answer:

LCM and HCF of 3,2.7 and 0.09 is 27 and 0.03 respectively.

Step-by-step explanation:

Given digits are 3,2.7 and 0.09

We can write 3 as $\frac{3}{1}$

and 2.7 as $\frac{27}{10}$

and 0.09 as $\frac{9}{100}$

Here we want to find HCF and LCM of these given numbers.

We know if $\frac{x}{y}$ and $\frac{a}{b}$ are two factions then HCF of these two numbers is $\frac{hcf \: of \: x \: and \: a}{lcm \: of \: y \: and \: b}$

And LCM of these two numbers is

$\frac{LCM \: of \: x \: and \: a}{HCF \: of \: y \: and \: b}$

Now HCF of $\frac{3}{1} ,\frac{27}{10} ,\frac{9}{100}$ is

$\frac{HCF \: of \: 3,27,9}{LCM \: of \: 1,10,100} \\ = \frac{3}{100} = 0.03$

and LCM of $\frac{3}{1} , \frac{27}{10} , \frac{9}{100}$ is

$\frac{LCM \: of \: 3,27,9}{HCF\: of \: 1,10,100} \\ = \frac{27}{1} = 27$

Extra information,

HCF means Highest Common Factor

and LCM means Largest Common Multiples.
