sidenote- please do not copy and paste this or else the answer is worthless

Answer 1

1 kilometer = 6.68 ×
`10^(-9)` (<<<AU is in scientific notation here)

To convert 300 billion kilometer (3,000,000,000 km) into AU you must multiply the kilometer by the equivalent of 1 km in AU (6.68 ×
`10^(-9)`)

3,000,000,000 × (6.68 ×
`10^(-9)`) = 20.04 AU

Hope this helped!
