Question

[(1/2+2/3+5/6) :7/12-2/5x5/6]x1/4:(5x12/25-1x1/3)multumesc​

Answer 1

(2x12/7-1/3)x1/4:(12/5-1/3)=(24/7-1/3)x1/4:31/15=65/21x1/4x15/31=65/7x1/4x5/31=325/868

Answer 2

$\left[\left(\frac{1}{2}+\frac{2}{3}+\frac{4}{6}\right)\div \frac{7}{12}-\frac{2}{5}\cdot \frac{5}{6}\right]\frac{1}{4}\div \left(5\cdot \frac{12}{25}-1\cdot \frac{1}{3}\right)$

$=\left[\left(\frac{1}{2}+\frac{2}{3}+\frac{2}{3}\right)\div \frac{7}{12}-\frac{2}{5}\cdot \frac{5}{6}\right]\frac{1}{4}\div \left(5\cdot \frac{12}{25}-1\cdot \frac{1}{3}\right)$

$=\frac{59}{21}\cdot \frac{1}{4}\div \left(5\cdot \frac{12}{25}-1\cdot \frac{1}{3}\right)$

$=\frac{59}{21}\cdot \frac{1}{4}\div \frac{31}{15}$

$=\frac{295}{868}$
