-5/14 × 1 1/20 + (-3/4) × 2 2/3 ​

Answer 1

$- \frac{5}{14} \times 1 \frac{1}{20} + ( - \frac{3}{4} ) \times 2 \frac{2}{3} = - \frac{5 \times 21}{14 \times 20} - \frac{3 \times 8}{4 \times 3} = - \frac{1 \times 3}{2 \times 4 } - \frac{1 \times 2}{1 \times 1} = - \frac{3}{8} - 2 = - 2 \frac{3}{8} = - 2.375$
