Stephen buys a melon and divides it into 6 servings. he eats one third of the melon over the weekend. how many slices of melon does stephen eat over the weekened?

Let

a = melon

b = servings of melon

c = slice of melon

equation 1

a = 6b

equation 2

a = cb

equation 3

2/3a=a-1/3a

2/3 = 6b-1/3a

2/3cb = 6b-1/3cb

6b = cb

c = 6 slices

There are 6 slices per serving, thus Stephen ate 6 slices over the weekend
