Explicație pas cu pas:
[tex]2 \times \frac{1}{3} \times \frac{4}{7} \times \frac{5}{9} \div 3 - \frac{1}{12} = \frac{7}{3} \times \frac{1}{3} \times \frac{4}{7} \times \frac{5}{9} \div 3 - \frac{1}{12} = \frac{7}{3 } \times \frac{1}{3} \times \frac{36}{63} \times \frac{35}{63 } = \frac{7}{3} \times \frac{1260}{63} = \frac{63}{27} \times \frac{1260}{63} = \frac{1260}{27} [/tex]
