$$ \frac{2}{5} \cdot 60 = \frac{2 \cdot 60}{5} = \frac{120}{5} = 24 $$
$$ \frac{5}{14} \cdot 84 = \frac{5 \cdot 84}{14} = \frac{420}{14} = 30 $$
$$ \frac{7}{12} \cdot 96 = \frac{7 \cdot 96}{12} = \frac{672}{12} = 56 $$
$$ 6 \% \cdot 110 = \frac{6}{100} \cdot 110 = \frac{6 \cdot 110}{100} = \frac{660}{100} = 6.6 $$
$$ 50 \% \cdot 110 = \frac{50}{100} \cdot 110 = \frac{50 \cdot 110}{100} = \frac{5500}{100} = 55 $$
$$ 190 \% \cdot 110 = \frac{190}{100} \cdot 110 = \frac{190 \cdot 110}{100} = \frac{20900}{100} = 209 $$
$$ 290 \% \cdot 110 = \frac{290}{100} \cdot 110 = \frac{290 \cdot 110}{100} = \frac{31900}{100} = 319 $$
