Let's assume
length of Ribbon A is A
length of Ribbon B is B
length of Ribbon C is C
we are given
A=B+20% of B
A=1.2B
B=C-20% of C
B=0.80C
now, we can find relation between A and C
A=1.2B
we can plug B
A=1.2*0.80C
A=0.96C
so,
Ribbon A is 4 % shorter than Ribbon C.......Answer
First you need to know the weight in Kilograms of one liter of the substance. Then you multiply that number by 192. For example, water weighs 1 kg per liter. This is an easy conversion, with 192 liters of water weighing 192 kilograms. The weight varies by substance, though, so you need to look up how much what you want weighs.
