Question

Add the product of - 1 upon 2 and -3 upon 5 to -11 upon 20 ​

Answer 1

Answer:

$\frac{ - 1}{4} or - 0.25$

Explanation:

$\frac{ - 1}{2} \times \frac{ - 3}{5} + \frac{ - 11}{20}$

$\frac{3}{10} + \frac{ - 11}{20}$

$\frac{3 \times 2}{10 \times 2} + \frac{ - 11 \times 1}{20 \times 1}$

$\frac{6}{20} + \frac{ - 11}{20}$

$\frac{ - 5}{20} = \frac{ - 1}{4}$

$\frac{ - 1}{4} = - 0.25$
