Answer 1

$(a). \frac{18}{23} + \frac{19}{23} + \frac{( - 3)}{23} \\ \\ \frac{18}{23} + \frac{ 19 }{23} - \frac{3}{23} \\ \\ \frac{37}{23} - \frac{3}{23} \\ \\ = \frac{34}{23}$

$(b). \frac{9}{19} \times 28 \\ \\ = \frac{252}{19}$

$(c).9 \frac{5}{7} - 2 \frac{2}{7} - 1$

Change into Improper Fraction

$\frac{68}{7} - \frac{16}{7} - 1 \\ \\ \frac{68}{7} - \frac{16 - 1 \times 7}{7} \\ \\ \frac{68}{7} - \frac{9}{7} \\ \\ = \frac{59}{7}$

$(d).2 \frac{7}{20} \times 8 \\ \\ \frac{47}{ \cancel{20}} \times \cancel 8 \\ \\ \frac{47}{5} \times 2 \\ \\ \frac{94}{5}$
