Sean and his sister, betty equally mow 8/9th the total area of a lawn. what fraction of the total area did each of them mow? (show ur work plz)

Since they mowed of the lawn in two equal parts, we need to split the pieces that were mowed into two equal groups. We know that in total they mowed 8 out of the total 9 pieces of lawn, so two equal groups that make 8 would be of size 4, since . Then they each mowed of the lawn.
