First I listed the weight of each watermelon:
1) Front, 7.35 kg
2) Left, 8.20 kg
3) Right, 6.45 kg

I next turned the kilograms weights to grams:

1) 7.35g = 7350
I did it in steps,7 first then the point 35.

2) 8.20 = 8200
8 first then the 2.I did the same steps here and below.

3) 6.45 = 6450

1) Front, would get 7350 points
2) Left, would get 8200 points
3) Right, would get 6450 points

The winner would be the one on the left!
