Melanie baked 10 batches of brownies, with 20 brownies in each batch. She set aside 3/4 of the brownies in each batch for a bake sale, put 3/5 of the remaining in a container, and gave out the rest. How many brownies are given out?
Melanie set aside 20 x 3/4 = 
<gadget id="calculator">20*3/4</gadget>
<output>15</output>
15 brownies from each batch for a bake sale.
So, there are 20 - 15 = 
<gadget id="calculator">20-15</gadget>
<output>5</output>
5 brownies that are not for bake sale from each batch.
Out of the 5, 5 x 3/5 = 
<gadget id="calculator">5*3/5</gadget>
<output>3</output>
3 brownies are kept in a container from each batch.
Thus, 5 - 3 = 
<gadget id="calculator">5-3</gadget>
<output>2</output>
2 brownies are given out from each batch.
Therefore, a total of 2 x 10 = 
<gadget id="calculator">2*10</gadget>
<output>20</output>
20 brownies are given out from the 10 batches.
