Answer 1

Answer:———————————

$\frac{7}{4} \times ( \frac{3}{10} - \frac{7}{9}) \\ = > \frac{7}{4} \times ( \frac{3 \times 9}{10 \times 9} - \frac{7 \times 10}{9 \times 10} ) \\ = > \frac{7}{4} \times ( \frac{27}{90} - \frac{70}{90} ) \\ = > \frac{7}{4} \times ( \frac{27 - 70}{90} ) \\ = > \frac{7}{4} \times ( \frac{ - 43}{90} ) \\ = > \frac{ - 301}{360}$
