Question #2) 7085g=_kg _g

Kg means kilo grams. kilo means 1000 so 1 kilogram is 1000 grams so

7085grams

conversion from grams to kilograms=kg/1000g

so 7085g times kg/1000g=7085/1000 kg=7.085 kg

or if you want kg and g then find out how many times 1000 will go into 7085

it goes in 7 times so 7 kg

then there are 85 grams left over so

7kg and 85g
