Given:
Number of slices = 8 equal slices
REgan and Juanita will 5/8 of the melon.
Let's determine one way in which the girls could eat theat fraction of the melon.
Given that the melon is divided into 8 equal slices and they ate 5/8 of the melon, it means they both ate 5 slices out of the 8.
One way in which they could eat the fraction is that Regan ate 3 slices and Juanita ate 2 slices which makes it 5 slices.
Thus, we have the equation below;
Therefore, Regan could eat 3/8 of the melon, and Juanita could eat 2/8 of the melon.
ANSWER:
Regan could eat 3/8 of the melon, and
Juanita could eat 2/8 of the melon.
