ExplanationWe have the equation:
[tex]□\times6=420.[/tex]
1) To solve this equation, we divide both sides by 6:
[tex](□\times6)\div6=420\div6.[/tex]
2) Using the associative property for the division and simplifying, we have:
[tex]\begin{gathered} □\times(6\div6)=420\div6, \\ □\times1=420\div6, \\ □=420\div6. \end{gathered}[/tex]
We have solved the equation.
Answer
D. □ = 420 ÷ 6
