Answer 1

✔$\frac{9}{7} - \frac{8}{9}$ = $\frac{81 - 56 }{63}$ = $\frac{25}{63}$

⭐$\frac{15}{18} - \frac{6}{12}$ = $\frac{30 - 18}{36}$ = $\frac{12}{36}$ = $\frac{6}{18}$ = $\frac{3}{9}$ = $\frac{1}{3}$

Simplifico: $\frac{6}{18}$

Simplifico: $\frac{3}{9}$

Simplifico: $\frac{1}{3}$

✔$\frac{5}{6} - \frac{1}{9}$ = $\frac{15 - 2}{18}$ = $\frac{13}{18}$

⭐$\frac{7}{8} - \frac{7}{10}$ = $\frac{35 - 28}{40}$ = $\frac{7}{40}$


✔$3\frac{4}{7} - 2\frac{3}{5}$ = $\frac{25}{7} - \frac{13}{5}$= $\frac{125 - 91}{35}$ = $\frac{34}{35}$

⭐$2\frac{3}{10} - 1\frac{4}{15}$ = $\frac{23}{10} - \frac{19}{15}$= $\frac{69 - 38}{30}$ = $\frac{31}{30}$
