Answer 1

Answer:

2.06

Step-by-step explanation:

The given expression is:

43.6 ÷ 21.2

This can be re-expressed as:

`\begin{gathered} (436)/(10)/(212)/(10) \\ \\ \end{gathered}`

Which can be further expressed as:

`\begin{gathered} \frac{436}{\cancel{10}}*\frac{\cancel{10}}{212} \\ \\ =(436)/(212) \\ \\ =2.06 \end{gathered}`

Note that the answer is in 3 significant figures because each of the terms in the expression given is in three significant figures
