$(7 - \frac{56}{36} \div \frac{43}{6} ) \times \frac{6}{7} = 5 \frac{35}{43} \\ \\ 1) \frac{56}{36} \div \frac{43}{6} = \frac{56}{36} \times \frac{6}{43} = \frac{56}{258} \\ \\ 2)7 - \frac{56}{258} = 6 \frac{202}{258} \\ \\ 6 \frac{202}{258} \times \frac{6}{7} = \frac{1750}{258} \times \frac{6}{7} = \frac{250}{43} = 5 \frac{35}{43}$
