Answer 1

Respuesta:

$\frac{42}{15} \times \frac{24}{7} = \frac{42 \times 24}{15 \times 7} = \frac{1008}{105} = \frac{336}{35} = \frac{48}{5} = 9 \frac{3}{5}$

$\frac{11}{45} \times \frac{75}{44} = \frac{11 \times 75}{45 \times 44} = \frac{825}{1980} = \frac{165}{396} = \frac{55}{132}$

$\frac{54}{12} \times \frac{28}{3} = \frac{54 \times 28}{12 \times 3} = \frac{1512}{36} = 42$

$\frac{2}{14} \times \frac{35}{8} = \frac{2 \times 35}{14 \times 8} = \frac{70}{112} = \frac{35}{56}$

$\frac{50}{9} \times \frac{36}{48} = \frac{50 \times 36}{9 \times 48} = \frac{1800}{432} = \frac{450}{108} = \frac{25}{6} = 4 \frac{1}{6}$

$\frac{6}{25} \times \frac{55}{18} = \frac{6 \times 55}{25 \times 18} = \frac{330}{450} = \frac{33}{45} = \frac{11}{15}$
