Answer
False.
Work Step by Step
$\frac{6}{14} = \frac{18}{45}$
We need to find this proportion is True or False.
First we need to convert both sides into lowest terms
i.e.
$\frac{6}{14} = \frac{6\div2}{14\div2} = \frac{3}{7}$
$\frac{18}{45} = \frac{18\div9}{45\div9} = \frac{2}{5}$
Now, As $\frac{3}{7} \ne \frac{2}{5}$, the given proportion is False.
