Ken has 7 baseballs. Each baseball weighs 0.3 pound . Ken wants to use this model to find the total weight of the baseballs. Eac

Step-by-step explanation:

Given:

Ken owns 7 baseballs.

Each baseball weighs 0.3 pounds.

If one ball weighs 0.3 pounds,

then 7 baseballs weigh 7 × 0.3 pounds,

which sums to 2.1 pounds.

Therefore, the total mass of the 7 baseballs is 2.1 pounds.

To illustrate this using boxes as per the provided information:

Considering the weight involves decimals,

assign 1 square box as equivalent to 0.1 pounds.

Answer:

1. For a single baseball weighing 0.3 pounds, Ken should shade 3 boxes.

Since 1 box corresponds to 0.1 pounds,

3 boxes equal 0.3 pounds.

2. To depict the combined weight of seven baseballs (2.1 pounds), Ken must shade this set of boxes seven times.

This means shading 3 boxes per baseball, repeated 7 times.

This explains how the shaded area in the second part compares to the first.

3. The shaded model represents the expression 0.3 × 7.

4. The total weight of the baseballs is 2.1 pounds.

Answer:

Detailed explanation:

Given:

Ken owns 7 baseballs,

each weighing 0.3 pounds.

If 1 baseball weighs 0.3 pounds,

then 7 baseballs weigh 7 × 0.3 pounds,

which equals 2.1 pounds.

Therefore, the combined weight of the 7 baseballs is 2.1 pounds.

To illustrate this with boxes as specified,

note that the weights involve decimals.

Assign one square box to represent 0.1 pounds.

Answer:

1. Representing the weight of one baseball (0.3 pounds) requires shading 3 boxes.

Since 0.1 pounds equals 1 box,

3 boxes correspond to 0.3 pounds.

2. To depict the total weight for all seven baseballs (2.1 pounds), shade the 3 boxes seven times.

This means shading 3 boxes per baseball, repeated for all 7 baseballs.

This illustrates how the shading amount in the second part compares to the first part.

3. The shaded portion visually represents the multiplication 0.3 × 7.

4. The overall weight equals 2.1 pounds.
