The ratio between Earth’s distance from the Sun and its scaled distance can be used to find the scaled distance for the other planets. Earth’s distance of 149.6 million kilometers to the Sun is scaled to 5.0 sheets of toilet paper as shown in the table. Now let’s find the scaled distance between Mars and the Sun as an example. Using the calculations shown, Mars’s distance to the Sun of 227.9 million kilometers would be scaled to 7.6 sheets of toilet paper.


d × 149.6 = 227.9 × 5.0
d = 7.6 sheets

Use this same process to complete the table with the scaled distances for the other planets. Round each answer to the tenths place. If you need additional math help, visit the Proportions section of the Math Review.
