Answer:

\boxed{\sf \cfrac{11}{5}\:\: or \:\: 2.2}

Step-by-step explanation:

\sf \left(\cfrac{-11}{20}\right)\div \left(\cfrac{-4}{16}\right)

Apply fraction rule:

\boxed{\sf\cfrac{a}{b}\div\cfrac{c}{d}  =\frac{a\times \:d}{b\times \:c}}

\longmapsto\sf \cfrac{-11\times \:16}{20\left(-4\right)}

Cancel the common factor of 16 and 20:

\longmapsto\sf \cfrac{-11\times4}{5\times(-4)}

Cancel common factor of 4 and  −4:

\longmapsto\sf \cfrac{-11}{5\times (-1)}

Multiply 5 by -1:

\longmapsto\sf \cfrac{-11}{-5}

Dividing two negative values gives a positive value:

\longmapsto\sf \cfrac{11}{5}

Or

\longmapsto\sf 2.2

Elina [12.6K]

Answer:

8 bags.

Step-by-step explanation:

Each bag will contain 27/3 = 9 pounds of quartz and 21/3 = 7 pounds of marble.

So there are 72/ 9 = 8 bags which contain  72 pounds of quartz. They will contain 56 pounds of marble, not 52 pounds.
