Question

divide the sum of (-13/5) and (12/7 by the product of (-21/7) and (-1/2
​

Answer 1

Step-by-step explanation:

$(\frac{ - 13}{5} + \frac{12}{7} )\div ( \frac{ - 21}{7} \times \frac{ - 1}{2} ) \\ ( \frac{ - 91 + 60}{35} ) \times ( \frac{14}{21} ) \\ \frac{ - 31 \times 2}{5 \times 21} \\ - \frac{ 61}{105}$

Answer 2

Malleability is a substance's ability to deform under pressure (compressive stress). If malleable, a material may be flattened into thin sheets by hammering or rolling. Examples of malleable metals are gold, iron, aluminum, copper, silver, and lead.
