Explicație pas cu pas:

$[3.(3) + 1.5 \times \frac{1}{2}] \div \frac{7}{3} - \frac{7}{4} =$

$= (\frac{33 - 3}{9} + \frac{3}{2} \times \frac{1}{2})\times \frac{3}{7} - \frac{7}{4}$

$=(\frac{30}{9} + \frac{3}{4})\times \frac{3}{7} - \frac{7}{4}$

$=(\frac{10}{3} + \frac{3}{4})\times \frac{3}{7} - \frac{7}{4}$

$=\frac{10 \times 4 + 3 \times 3}{3 \times 4}\times \frac{3}{7} - \frac{7}{4}$

$=\frac{40 + 9}{12}\times \frac{3}{7} - \frac{7}{4}$

$=\frac{49}{12}\times \frac{3}{7} - \frac{7}{4}$

$= \frac{7}{4} - \frac{7}{4} = 0$
