Answer:
[tex]\large \boxed{\text{460 dg}}[/tex]
Explanation:
1. Convert decagrams to grams
[tex]\text{Mass} = \text{4.6 dag} \times\dfrac{\text{10 g}}{\text{1 dag}} = \text{46 g}[/tex]
2. Convert grams to decigrams
\[tex]\text{Mass} = \text{46 g} \times\dfrac{\text{10 g}}{\text{1 dg}} = \text{460 dg}\\\\\large \boxed{\textbf{4.6 dag = 460 dg}}[/tex]
