Question

верна ли пропорция 5 4\5 делить 9 1\2 равно 4 64 \ 100 делить 7 3\5

Answer 1

$5\frac{4}{5}:9\frac{1}{2}=4 \frac{64}{100}:7\frac{3}{5} \\\\\frac{29}{5}:\frac{19}{2}= \frac{464}{100}: \frac{38}{5}\\\\\frac{29}{5}* \frac{2}{19}= \frac{464}{100}* \frac{5}{38}\\\\\frac{58}{95}= \frac{232}{20}* \frac{1}{19}\\\\\frac{58}{95}= \frac{58}{5}* \frac{1}{19}\\\\\frac{58}{95}= \frac{58}{95}$

Пропорция верна.
