Explanation:

Step1: Understand the meaning of the figures

The figure \(1,300,000\) under the Earth represents the number of Earth - sized spheres that can fit inside the Sun. The figure \(= 1\) under the Sun means that the Sun is taken as one whole unit in this relative - size comparison.

Step2: Analyze the relationship

If we consider the volume (since when comparing the "size" in terms of how many of one can fit into the other, volume is a relevant measure in such a context), if \(V_{Sun}\) is the volume of the Sun and \(V_{Earth}\) is the volume of the Earth, we have the relationship \(V_{Sun}=1300000V_{Earth}\). The number \(1,300,000\) is a multiplier that shows the ratio of the volume of the Sun to the volume of the Earth. The \(= 1\) for the Sun is a normalizing factor. It is like saying if we consider the Sun's volume as a single entity (\(V_{Sun} = 1\) unit in this relative - scale), then the Earth's volume is \(\frac{1}{1300000}\) of that unit.

Answer:

The number \(1,300,000\) under the Earth indicates the number of Earth - sized volumes that can fit inside the Sun. The \(= 1\) under the Sun is a reference value. So, while the Sun is physically larger (in terms of volume), the \(1,300,000\) is a ratio (Sun's volume to Earth's volume), and the \(= 1\) is a way of normalizing the Sun's volume for the purpose of showing the relative - size (volume) relationship.
