Solution

The correct option is A True
$6 : 4.5$ can be written as $\frac{6}{4.5}$
Lowest term of $\frac{6}{4.5} = \frac{60}{45}$ $= \frac{4}{3}$ ( Divide both terms by their HCF $15$ )
$4.8 : 3.6$ can be written as $\frac{4.8}{3.6}$
Lowest term of $\frac{4.8}{3.6} = \frac{48}{36}$ $= \frac{4}{3}$ ( Divide both terms by their HCF $12$ )
Since both are equal.
Hence, it is true that $6 : 4.5 : : 4.8 : 3.6$
