Answer: 9/20
Step-by-step explanation:
From the question, we are informed that Margaret has 3 3/5 pieces of cake left over from her birthday and that she wants to divide the remainig cake equally among her 8 friends.
The amount of cake that each friend receive will be:
= 3 3/5 ÷ 8
= 18/5 ÷ 8
= 18/5 × 1/8
= 18/40
= 9/20
Each friend will receive 9/20 piece of cake.
