Worked solution

1. Compare $0.5$ with $\frac{5}{9}$ and choose the correct inequality symbol.

$0.5=\frac{1}{2}=\frac{4.5}{9}$

Since $\frac{4.5}{9}<\frac{5}{9}$ ,

$0.5<\frac{5}{9}$

Answer

$<$

1. Find the lower bound of a distance rounded to the nearest 10 cm.

Nearest $10$ cm $= 0.1$ m, so half of this is $0.05$ m.

Least possible distance
$=12.5-0.05=12.45$

Answer

$12.45$ m
