Describe the Keep Change Flip method we use to divide fractions. Including an example would make your explanation even stronger!
To use the Keep Change Flip method, keep the first fraction the same, change the division to multiplication, and then flip the second fraction. (change to its reciprocal)
Example: 2/3 / 4/5 = 2/3 x 5/4
Describe how to plot the ordered pair (2, 3) on a coordinate grid.
Start at the origin (0,0). Movie to the right 2 for positive x-value, and then move up 3 from there for the positive y-value. Place the point there.
