How much more or less?4) Information in the table below could be used for drill and practice exercises indecimal computation. A similar table could be developed using the planets'average distances from the Sun.(\PLA~E:TOIAME:TEl2.Find thediameterof eachplanet.EARTH 12, 75G k.mMERCURY .38 , !:.A12T~:" DIAMETE.RVENU
