First we need to convert them into improper fractions
2 2/5= 12/5
6 4/5= 34/5
to divide fractions you flip the second one and multiply them
12 5 12
---- × ---- = -----
5 34 34
then simplify
12/34=6/17
the correct answer is 6/17
I hope I've helped!
We can not say that this areas are not civilized or to call them backwards. We may call them different. We can take for example the uses of animals in order to expand the commerce of their area. If we research about the use of camels, for example, we could see that it gained an special place within those who wanted to travel through many difficult areas like deserts. So in the case of camels they were not backwards, they used a different method to obtain success
Plate Tectonics, that would be the answer <span />
