Dok1199 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) $10- \frac{15}{26} =9 \frac{26}{26} - \frac{15}{26} =9 \frac{26-15}{26} =9 \frac{11}{26}$
