Explanation
We are given the following numbers:
[tex]\begin{gathered} 0.676 \\ 76.1 \end{gathered}[/tex]We are required to round the numbers to the nearest tenth and tens respectively.
We know that the number system can be represented as:
Therefore, we have:
[tex]\begin{gathered} 0.676 \\ where \\ 6=tenth \\ The\text{ }next\text{ }number\text{ }is\ge5\text{ }so\text{ }we\text{ }round\text{ }up\text{ }to\text{ }1 \\ \therefore0.676\approx0.700 \\ \\ 76.1 \\ where \\ 7=tens \\ The\text{ n}ext\text{ n}umber\text{ i}s\geqslant5\text{ s}o\text{ w}e\text{ r}ound\text{ u}p\text{ t}o\text{ 1} \\ \therefore76.1\approx80.0 \end{gathered}[/tex]Hence, the answers are:
[tex]\begin{gathered} 0.676\approx0.700 \\ \\ \begin{equation*} 76.1\approx80.0 \end{equation*} \end{gathered}[/tex]
