Answer: point
(5, 3) and (9, 3) (2, 3) and (7, 3)
Step-by-step explanation:
When all the coordinate are plotted on a graph, point (5, 3) and (9, 3) , & point (2, 3) and (7, 3) are found to be in a straight line. So Henry will count some units to find the distance between two points of the coordinate given above.
The whole melon = 5/5
ONE piece went to four children, so
how much of the melon the children got = 1/5
5/5 - 1/5 = 4/5
With 4/5 of the melon, she made 3 fruit cups
4/5 / 3 = 4/5 x 1/3 = 4/15
so she put 4/15 of the melon in the fruit cups
