In 2009, the world's largest pumpkin weighed 784 kilograms. An average-sized pumpkin weighs 5,000 grams. The 2009 world-record pumpkin weighs

5000 grams = 5 kilograms

# 784 -5 = 779# kilograms

Think of the metric system like a staircase.

#Kg = 1000 = 10^3 #
#....Hg = 100 = 10^2 #
#.....dkg = . 10 = ..10^1#
#...........g = ......1 = 10^0#
#.............dg = ...0.1 = 10^-1#
#................cg = ..0.01 = 10^-2 #
# .................mg= 0.001 = 10^-3#

To change from grams to kilograms move the decimal three places to the left. going from a smaller unit to a larger unit.

so # 5000 g = 5 kg#
