so my problem is 1/8k + 1/5k -1/4k = 3/20

My teacher said to find the LCD out of all the denominators.... would it be 40 or 40k because i tried solving it for both ways and I couldn't get the answer... so maybe the LCD is something different. can you help me?

Hi,
I would like to know how much C02 gaz was produced and released in the athmosphere by human (industrial) activities in a recent year, in gigatons ?

I would like to know also how much co2 was released in the same period of time by natural phenomenon (volcanoes, sea, biomass....)

Please quote your source.

Thanks,
Cyril
