There are 149597870691 meters in one AU. There are 100 cm in a meter.
So, all you gotta do is multiply 149597870691 by 1.5, then by 100. If you'd like to covert to Scientific after or before is your choice.
I am working through another portion of my math book and the question states.
Mars Orbits 1.5 AU (astronomical units) from the sun what is that distance in CM?
1 meter = 39.36 inches
1 inch = 2.54 centimeters
1 cm = .394 inches
I attempted it this way but the answer was incorrect.
Now where do I go from here? You do not have to solve for me but if someone would please show me the steps it would be much appreciated.
