amber had three eights of a cake left after her party.she wrapped a piece that was one fourth of the original cake for her best friend. what fractional part did she have left for herself.
So first, we want what she gave to her friend, 1/4 of the original cake. 1/4 is equal to 2/8, so 3/8-2/8 equals 1/8. She left 1/8 of the cake for herself.
