Anewly discovered solar system is found 300 billion kilometers from the sun. how many au does this represent? show your work.
sidenote- do not copy and paste this or else the answer is worthless

1 kilometer = 6.68 × (<<<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 × )

3,000,000,000 × (6.68 × ) =  20.04 AU

Hope this helped!
