I'm not really sure what the question you're asking is, but if you want to know how much would be left, the answer is 19/30 pounds of clay.
<em>u</em><em> </em><em>all</em><em> </em><em>r</em><em> </em><em>from</em><em> </em><em>Australia</em><em>.</em><em>.</em><em>.</em>
We know, divisor * quotient = Dividend
-7 * q = 56
q = 56/-7
q = -8
So, your final answer is -8
Hope this helps!
