The diameter of Earth is 12742 kilometers. If the model that represents the Earth has diameter of 1 inch, then the scale is:
1 inch = 12742 kilometers
Expressing this as a ratio, it becomes 1:12742.
The diameter of the moon is 3474 kilometers. To determine the diameter of the model of the moon in inches, assign a variable that represent it. Let it be x.
x inches = 3474 kilometers

The diameter of Earth is 12742 kilometers. If the model that represents the Earth has diameter of 1 inch, then the scale is:
1 inch = 12742 kilometers
Expressing this as a ratio, it becomes 1:12742.
The diameter of the moon is 3474 kilometers. To determine the diameter of the model of the moon in inches, assign a variable that represent it. Let it be x.
x inches = 3474 kilometers
Expressing it as a ratio, it becomes x:3747.
To solve for the value of x, set the two ratios equal to each other. Take note that when used in equations, the ratio should be in fraction form.
`x/3747=1/12742`
Isolating the x, the equation becomes
`x=1/12742*3747`
`x=0.2726`
Therefore, the diameter of the model of the moon is 0.2726 inch.
