Answer 1

Answer:

$\frac{ - 3}{5} + ( - 0.75) + 4 \times \frac{7}{10} \\ = \frac{ - 3}{5} - \frac{75}{100} + \frac{47}{10} \\ = \frac{ - 3}{5} - \frac{3}{4} + \frac{47}{10} \\ = \frac{4 \times - 3 - 5 \times 3 + 2 \times 47}{20} \\ = \frac{ - 12 - 15 + 94}{20} \\ = \frac{ - 27 + 94}{20} \\ = \frac{67}{20} \\ =3.35$
