Question

4. Grandpa Mick opened a pint of ice cream. He gave his youngest grandchild of the ice cream and his middle grandchild of the remaining ice cream. Then, he gave his oldest grandchild of the ice cream that was left after serving the others. a. Who got the most ice cream? How do you know? Draw a picture to support your reasoning.​

Answer 1

Explanation:

Let's assume that the pint of ice cream had a total of 16 scoops.

Grandpa Mick gave his youngest grandchild 1 scoop, which leaves 15 scoops.

Then, he gave his middle grandchild half of the remaining ice cream, which is 7.5 scoops (half of 15). This leaves 7.5 scoops.

Finally, he gave his oldest grandchild all the remaining ice cream, which is 7.5 scoops.

So the youngest grandchild got 1 scoop, the middle grandchild got 7.5 scoops, and the oldest grandchild got 7.5 scoops.

Therefore, the middle and oldest grandchild got the same amount of ice cream, which is the most. We can see this by drawing a picture with three equal sections representing the ice cream, and shading in the portions that each grandchild received. The middle and oldest portions will be the same size and larger than the youngest portion.
