1 - 3/282 - 6/80

1 - 3/282 - 6/803 - 7/22

1 - 3/282 - 6/803 - 7/224 - 28/60

Step-by-step explanation:

1..

$\frac{6}{7} - \frac{3}{4} = \frac{6 \times 4}{7 \times 4} - \frac{3 \times 7}{4 \times 7} \\ = \frac{24}{28} - \frac{21}{28} \\ = \frac{24 - 21}{28} \\ = \frac{3}{28}$2..

$\frac{7}{8} - \frac{8}{10} = \frac{7 \times 10}{8 \times 10} - \frac{8 \times 8}{10 \times 8} \\ = \frac{70}{80} - \frac{64}{80} \\ = \frac{70 - 64}{80} \\ = \frac{6}{80}$

3..

$\frac{1}{2} - \frac{2}{11} = \frac{1 \times 11}{2 \times 11} - \frac{2 \times 2}{11 \times 2} \\ = \frac{11}{22} - \frac{4}{22} \\ = \frac{11 - 4}{22} \\ = \frac{7}{22}$

4..

$\frac{8}{10} - \frac{2}{6} = \frac{8 \times 6}{10 \times 6} - \frac{2 \times 10}{6 \times 10} \\ = \frac{48}{60} - \frac{20}{60} \\ = \frac{48 - 20}{60} \\ = \frac{28}{60}$
