vovikov84 [41]

Answer:Enrico must multiply the distance of mars from sun (meters) with the 6.6844\times 10^{-12} to convert the distance in astronomical units.

Explanation:

1 astronomical unit  = 1.496\times 10^{11} m

1m=\frac{1}{1.496\times 10^{11} } AU=6.6844\times 10^{-12} AU

Let the distance between the sun and Mars be Y( meters)

Distance in AU= Y\times 6.6844\times 10^{-12} AU

Enrico must multiply the distance of mars from sun (meters) with the 6.6844\times 10^{-12} to convert the distance in astronomical units.
