Bonnie's orange was cut into 3/8 she ate 3/8 of the orange and her friend ate 3/8 of it did they eat the whole Orange

Answer 1

If each friend ate 3/8 of the orange, 3/8+3/8 = 6/8 The whole orange is 8/8

8/8-6/8 means there is 2/8 left. This reduces to 1/4 of the orange remains. They didn't eat the whole thing.
