Question

3 4/9 x 6 3/7 x 8/9 + 2 5/9 + 2 4/7​

Answer 1

Ответ:

$\frac{31}{9} \times \frac{45}{7} = \frac{155}{7} \\ \frac{155}{7} \times \frac{8}{9} = \frac{1240}{63} \\ \frac{1240}{63} + \frac{23}{9} = \frac{1240 + 161}{63} = \frac{1401}{63} \\ \frac{1401}{63} + \frac{18}{7} = \frac{1401 + 162}{63} = \frac{1563}{63} = 24 \frac{51}{63}$
