The total number of strawberries in the three baskets is 3*900 = <<3*900=2700>>2700
If 2/9 of the strawberries were remaining out of all the strawberries after the hedgehogs ate some, there were 2/9*2700 = <<2/9*2700=600>>600 strawberries remaining.
The total number of strawberries that the two hedgehogs ate is 2700-600 = <<2700-600=2100>>2100 strawberries.
If the hedgehogs ate an equal number of strawberries, each ate 2100/2 = <<2100/2=1050>>1050 strawberries.
