Joni should have divided by 10,000.
Solution:
1 deka = 10 units
=> 1 dekagrams = 10 g
1 centi = 0.01 unit
=> 1 centi gram = 0.01 g
=> 1 centi gram = 1/100 g
=> 100 centi gram = 1 g
=> 1 g = 100 centi gram
1 dekagrams = 10 g
1 g = 100 centi gram
=> 1 dekagrams = 10 x 100 centi gram
=> 1 dekagrams = 1000 centi gram
=> 67 dekagrams = 67x 1000 centi gram
Joni should have multiplied by 1,000
