Answer 1

1)25/4 или 6 целых 1/4
2)5/17
3)35/8 или 4 целых 3/8
4)124/15
5)2590/26

Answer 2

1)  7-$\frac{3}{4}$=6$\frac{4}{4} - \frac{3}{4}$ = 6$\frac{1}{4}$
2)  1-$\frac{12}{17} = \frac{17}{17}- \frac{12}{17}= \frac{17-12}{17}= \frac{5}{17}$
3)  $5- \frac{5}{8} =4 \frac{8}{8} - \frac{5}{8} =4 \frac{8-5}{8} =4 \frac{3}{5}$
4)  $9- \frac{11}{15} = 8 \frac{15}{15}- \frac{11}{15} =8 \frac{15-11}{15} =8 \frac{4}{15}$
5)  $10- \frac{15}{26} =9 \frac{26}{26} - \frac{15}{26} =9 \frac{26-15}{26} =9 \frac{11}{26}$
