Explicație pas cu pas:
[tex]a = (2 - 2 \frac{3}{4} \times \frac{2.25}{3.(6)}) \div \frac{1}{1.0(6)} = (2 - \frac{11}{4} \times \frac{225}{100} \times \frac{9}{36 - 3} )\times \frac{106 - 10}{90} = (2 - \frac{11}{4} \times \frac{9}{4} \times \frac{9}{33} ) \times \frac{96}{90} = (2 - \frac{27}{16}) \times \frac{16}{15} = \frac{32 - 27}{16} \times \frac{16}{15} = \frac{5}{15} = \frac{1}{3} [/tex]
