4 friends order their own personal pan pizzas. No one could finish but Abby ate 2/3, Bobby ate 7/8, Carly ate 3/7, and Danny ate 2/5 of their pizzas. How much did each person eat? Who ate the most, the least and who ate more than half? 

how much did each eat? Heck, they told you that.

Convert each fraction to decimal to compare. 0.5 is 1/2.

2/3 = 0.666
and so on

To find out how much each person ate, we need to calculate the fraction of their respective pizzas that they consumed. Let's calculate it for each friend:

1. Abby ate 2/3 of her pizza.
2. Bobby ate 7/8 of his pizza.
3. Carly ate 3/7 of her pizza.
4. Danny ate 2/5 of his pizza.

To compare the amounts, we can convert these fractions to a common denominator. The least common denominator for 3, 8, 7, and 5 is 840, so we will use that:

1. Abby ate (2/3) * (840/840) = 560/840 of her pizza.
2. Bobby ate (7/8) * (840/840) = 735/840 of his pizza.
3. Carly ate (3/7) * (840/840) = 360/840 of her pizza.
4. Danny ate (2/5) * (840/840) = 336/840 of his pizza.

Now let's simplify the fractions:

1. Abby ate 560/840 = 2/3 of her pizza.
2. Bobby ate 735/840 ≈ 7/8 of his pizza.
3. Carly ate 360/840 = 3/7 of her pizza.
4. Danny ate 336/840 = 2/5 of his pizza.

Therefore, Abby ate 2/3 of her pizza, Bobby ate 7/8 of his pizza, Carly ate 3/7 of her pizza, and Danny ate 2/5 of his pizza.

To find out who ate the most and the least, we can compare the fractions:

- Abby ate 2/3, Bobby ate 7/8, Carly ate 3/7, and Danny ate 2/5 of their respective pizzas.

Comparing the fractions, we can see that Bobby ate the most (7/8), Abby ate the second most (2/3), Danny ate the third most (2/5), and Carly ate the least (3/7).

To determine who ate more than half, we need to check which fractions are greater than 1/2.

From the calculations, we can see that Abby (2/3) and Bobby (7/8) both ate more than half of their pizzas. Carly (3/7) and Danny (2/5) did not eat more than half of their pizzas.

In summary:
- Abby ate 2/3 of her pizza.
- Bobby ate 7/8 of his pizza.
- Carly ate 3/7 of her pizza.
- Danny ate 2/5 of his pizza.
- Bobby ate the most, Carly ate the least, and Abby and Bobby ate more than half of their pizzas.
