Make a table of the eight planets with the columns name, kind (the first four are rocky, the last four giant) and mass in Earth masses: 0.055, 0.815, 1.0, 0.107, 317.8, 95.2, 14.5 and 17.1. List the names of the giant planets with a mass above 50, from the heaviest to the lightest.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Plan. Two conditions joined with &, each in brackets. Then sort by the mass, from the largest.
Check. The giants are Jupiter, Saturn, Uranus and Neptune. Only Jupiter (317.8) and Saturn (95.2) have a mass above 50.
Answer: ['Jupiter', 'Saturn'].
