So the method is clearly stating that we need to round to the nearest ten, so let's round using the rule set.
- If the number is below 5, round down.
- If the number is 5, round up.
- If the number is above 5, also round up.
This array should help you vision the sequence better.
⇒ [tex]\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
Now, using the rounding ruleset, we have to find what to round to. Since 32 and 12 both have a ones digit below 5, we round down, meaning we now have 30 and 10. The last step is to multiply 30 by 10 to get your estimate.

[tex]*~10[/tex]

[tex]300[/tex]
With this information, your answer is 300(rounded to nearest ten)!
