9 this is because in this equation we need to work out how many ninths there are in one whole. Our model shows one whole square. To divide it into nine equal parts. Each of these equal parts is a ninth. We have three ninths on the top row. Another three ninths on the second rows makes six ninths altogether. And three more ninths on the but to row makes a total of nine ninths equal one whole. We drew a square and we divided it into nine equal parts. Nine ninths equals one whole.
