Ascientist splits 9 liters of pond water among 10 jars. the jars have the same amount, how many millimeters of pond water in each jar

Sounds like your gonna need to divide the 9 liters by the ten jars, to do that they need to be in the same measurements though so first find how many liters fill a jar and once you have a standard and equal way of measuring the jar and liters amounts then divided the 9 liters by the 10 jars and it should show you, othewise find out what percent of the pond water goes into the jars in each one when it's divided
