Answer 7

And what is 100*2 ?

Answer 8

200

Answer 9

Okay...

Answer 10

Answer 11

is 200 the right answer

Answer 12

Good thinking. Nope your approach is correct.

Answer 13

I was thinking about how to get rid of the fraction rather than finding the LCM. My mistake.

Answer 14

is 200 or 100 the correct answer ?

Answer 15

100

Answer 16

ok thanks

Answer 17

Now you can't say noone helped you.

Answer 18

WAIT

Answer 19

LCM is for INTEGER multiples

Answer 20

100 is not 'multiple' of 200/3 in this sense

Answer 21

u mean the question is wrong

Answer 22

No - I mean the answers above are wrong

Answer 23

200 is the answer ?

Answer 24

yes

Answer 25

LCM: least common multiple. The quantities 200/3 and 100 have a common multiple (a factor common to both). What is it?

Answer 26

@mathmale

I think you are confusing LCM with HCF

we are not concerned with 'factors' here except to say that both numbers are factors of the LCM :-)

Answer 27

@MrNood, I have not seen any definition of LCM that states that the multiplier has to be an integer.

Answer 28

@Hero

If that were the case then the LCM would always be equal to the larger number - because if you have 2 numbers a & b you can always multiply a by b/a to get b

Review your comcept of LCM and see if you now agree.

Answer 29

^^

or even the SMALLER number - for the same reasoning

Answer 30

Actually, according to the definition posted on Wikipedia, all the numbers are supposed to be integers. So this question itself might be a trick one.

Answer 31

https://en.wikipedia.org/wiki/Least_common_multiple

Answer 32

However THUS reference implies that it is a valid concept for RATIONAl numbers - not just integers

I don't have an opinion on this - but either way - 200 is the answer above.
