Answer
1. It is wrong because $\frac{24}{32}$ is not equal to $\frac{24}{30}$
2. $\frac{12}{16},\frac{18}{24}, \frac{24}{32}, \frac{30}{40}$
Work Step by Step
1. In order to prove that this is not true, we must make the numerator or the denominator the same the the example's; ie $\frac{6}{8} = \frac{6\times4}{8\times4} = \frac{24}{32}$
This proves it wrong because $\frac{24}{32}$ is not equal to $\frac{24}{30}$
2. To create a true proportion of this fraction, you need to multiply the top and bottom by the same
number, eg $\frac{6}{8} = \frac{2\times6}{2\times8} = \frac{12}{16}$
$\frac{6}{8} = \frac{3\times6}{3\times8} = \frac{18}{24}$
$\frac{6}{8} = \frac{4\times6}{4\times8} = \frac{24}{32}$
$\frac{6}{8} = \frac{5\times6}{5\times8} = \frac{30}{40}$
