Question

If each square that is broken into 100 parts is considered a whole, which model represents 0.68 of 2?

2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray.
2 models divided into 100 parts. Left: 70 are shaded dark gray. 30 are shaded light gray. Right: 0 are shaded dark gray. 40 are shaded light gray.
2 models divided into 100 parts. Left: 60 are shaded dark gray. 40 are shaded light gray. Right: 20 are shaded dark gray. 20 are shaded light gray.
2 models divided into 100 parts. Left: 100 are shaded gray. Right: 100 are shaded gray.

Answer 1

The correct model representing 0.68 of 2 is the one where there are 2 models divided into 100 parts each, with 68 parts shaded gray in both the left and right squares, totaling 136 parts shaded.

Step-by-step explanation:

The question is asking to identify which model represents 0.68 of 2 when each model is divided into 100 equal parts and each part represents 0.01. Therefore, to represent 0.68 of a whole, 68 parts should be shaded. Since we are looking for 0.68 of 2 wholes, we need two of these models, so a total of 136 parts should be shaded to represent 0.68 of 2.

The correct model is the first one described: 2 models divided into 100 parts. Left: 68 are shaded gray. Right: 68 are shaded gray. Each square represents one whole, which means each square has 100 parts and 0.68 of that square would be 68 parts shaded. Since there are two squares representing two wholes, 68 parts shaded in each square would correctly represent 0.68 of 2.

Answer 2
