# The Lipstick Sisters Cousins' Weight

#### Difficulty: Easy

The numbers in the picture above show how much the Lipstick Sisters & their 4 cousins weigh on the planet Earth. However, they live on Photonis(nicknamed Blueworld), which is thrice as small as Earth, so its gravity is only **1/3** as strong. That means that the 6 ladies will be **3 times** lighter on their home planet than on Earth. (That's what *thrice* means: 3 times!) Math must be used to answer the questions below.

### Questions:

- What is the sum of the weight of all 6 ladies? (If they were on the planet Earth?)
- What is the sum of the weight of all 6 ladies? (If they were on the planet Photonis?)
- Who is the lightest?
- Who is the heaviest & the only cousin who is heavier than both Danielle & Michelle?
- True or False? From left to right, the weights of Danielle & Michelle's 4 cousins go from lightest to heaviest.
- How much does each lady weigh on Photonis?
- What is the average Earth weight between all 6 of them?
- What is the average Photonis weight between all 6 of them?
