1. After saving up for while, Melanie saved $12 of her allowance. She decided to spend 1/3 of that money at the book fair. the book she wanted was $5. Did she bring enough money to buy the $5 book. Draw a model to justify your answer.
Answer - 12 x 1/3 = 12/3 =4. So she doesn't have enough. But, how do I show that in a model?
