Joni has a box that a mass of 67 dekagrams she converts this to centigrams her work is shown below

Answer:
Joni should have multiplied by 1000.
Step-by-step explanation:
Converting from dekagrams to centigrams is going from a larger to a smaller measure.
We know that 1 dekagram = 10 grams, and 1 gram = 100 centigrams; this means that 1 dekagram = 10(100) = 1000 centigrams.
We multiply this by 67:
67(1000) = 67000 centigrams.
The statement which describes Joni's error is; Choice B; Joni should have multiplied by 1000.
Since the box Joni has has a mass of 67 dekagrams.
In essence, since the conversion factor of a dekagram to a unit gram is 10.
Therefore, 67 dekagrams = 67 × 10 grams.
= 670 grams.
The conversion of grams to centigrams requires multiplication by a conversion factor of 100.
= 670 × 100 centigrams.
= 67000 centigrams.
Ultimately, to convert 67 dekagrams to centigrams; We need to multiply by 1000.
Therefore, the statement which describes Joni's error is; Choice B; Joni should have multiplied by 1000.
