Answer :

We were told that Four hamsters have a combined weight of 5.112 grams. We know that

1000 grams = 1 kilogram

Thus,

5.112 grams = 5.112/1000

= 0.005112 kilograms

Since all the hamsters weigh the same, then the weight of one hamster is

0.005112 /4

= 0.001278 kilogram

The weight of one hamster is 0.001278 kilogram
