1. a 0.5-pound object weighs one half as much as a 1-pound object.
if a cheeseburger weighs a half pound on earth, what will it weigh
on jupiter?

Answer=7:13

Kenny's Weight*6/7=Melvin's Weight

So, for example, if Melvin's weigh was 7...

Kenny's Weight*6/7=7

divide both sides by 6/7

Kenny Weight=6

So we can say that Melvin's weight to Kenny's weight is 7:6

The boys total weights would be...

7+6=13

So Melvin's weight over the total weight of the two boys is:

7:13
