The minimum number of train cars needed is 8 because 112 multiplied by 8 is 896 which means 7 trains will be full and the last one will only carry 108 crates

0.0900-0.0088=0.0812
I did it by thinking of it as 900-88=812
Add the three numbers together, then divide by 3 because there are 3 numbers.
66+62+82= 210 = 70
70 is the average of these 3 numbers.
Hope this helps! :)
