Point a is at –4 and point b is at 6. which describes one way to find the point that divides ab into a 3: 2 ratio? for a ratio of 3: 2, divide ab into 3 equal parts. each equal part is 3 units, so the point that divides ab into a 3: 2 ratio is 0. for a ratio of 3: 2, divide ab into 3 equal parts. each equal part is 3 units, so the point that divides ab into a 3: 2 ratio is 3. for a ratio of 3: 2, divide ab into 5 equal parts. each equal part is 2 units, so the point that divides ab into a 3: 2 ratio is 1. for a ratio of 3: 2, divide ab into 5 equal parts. each equal part is 2 units, so the point that divides ab into a 3: 2 ratio is 2.
