False. Because the dominator is multiplied by the numerator. To solve the proportion we should cross multiply:

\(\displaystyle{24}\times{m}={8}\times{15}\)

\(\displaystyle{m}=\frac{{{8}\times{15}}}{{24}}\)

m=5

\(\displaystyle{24}\times{m}={8}\times{15}\)

\(\displaystyle{m}=\frac{{{8}\times{15}}}{{24}}\)

m=5
