Answer 1

$\displaystyle5\frac{1}{3}-3\frac{4}{9}=\frac{16}{3}-\frac{31}{9}=\frac{48-31}{9}=\frac{17}{9}=1\frac{8}{9}$

Answer 2

Пошаговое объяснение:

$5 \frac{1}{3} - 3 \frac{4}{9} = \frac{1 + 5 \times 3}{3} - \frac{4 + 3 \times 9}{9} = \frac{16}{3} - \frac{31}{9} = \frac{16 \times 3}{3 \times 3} - \frac{31 \times 1}{9 \times 1} = \frac{48}{9} - \frac{31}{9} = \frac{48 - 31}{9} = \frac{17}{9} = \frac{1 \times 9 + 8}{9} = 1 \frac{8}{9}$
