Answer 1

$\displaystyle1 \frac{2}{9} + \frac{2}{9} - \frac{34}{45} = \frac{11}{9} + \frac{2}{9} - \frac{34}{45} = \frac{11 + 2}{9} - \frac{34}{45} = \frac{13}{9} - \frac{34}{45} = \frac{65 - 34}{45} = \frac{31}{45} .$

Answer 2

Объяснение:

$1 \frac{2}{9} + \frac{2}{9} - \frac{34}{45} =\frac{9+2}{9}+\frac{2}{9}-\frac{34}{45} =\frac{11}{9}+\frac{2}{9}-\frac{34}{45} =\frac{11+2}{9}-\frac{34}{45} =\frac{13}{9}-\frac{34}{45} =\frac{65}{45}-\frac{34}{45} =\frac{65-34}{45} =\frac{31}{45}$
