Answer:
3854g
Step-by-step explanation:
To calculate the difference, we have to convert the weight in same unit.
=> 1kg = 1000g
Therefore,
Weight of dog1 = 3090g
Weight of dog2 = 746g
Weight of dog3 = 4.6 kg = 4.6 * (1000)g = 4600g
So the dog3 is heaviest while dog2 is lightest.
The difference in weight from lightest to heaviest is = 4600 - 746 = 3854g
