1)6 7/15-2 3/15
2)9 11/16+4 3/16-2 2/16
3) 15 7/10+2 2/10-4 1/10

Answer 1

1) $6 \frac{7}{15} -2 \frac{3}{15} = 6 - 2 \frac{7-3}{15} = 4 \frac{4}{15}$
2) $9 \frac{11}{16} +4\frac{3}{16} -2\frac{2}{16} = 9 + 4 - 2 \frac{11+3-2}{16} = 11 \frac{12}{16} = 11 \frac{3}{4}$
3) $15 \frac{7}{10} +2\frac{2}{10} -4 \frac{1}{10} = 15+2-4 \frac{7+2-1}{10} = 13 \frac{8}{10} = 13 \frac{4}{5}$
Надеюсь, помог
