Explanation:

The total number of kilograms of flour

[tex](2\times3)+(3\times3\frac{1}{2})+(1\times4)+(6\times4\frac{1}{2})[/tex][tex]6+(3\times\frac{3\times2+1}{2})+4+(6\times\frac{4\times2+1}{2})[/tex][tex]6+(3\times\frac{7}{2})+4+(6\times\frac{9}{2})[/tex][tex]6+\frac{3\times7}{2}+4+(3\times9)[/tex][tex]6+\frac{21}{2}+4+27[/tex][tex]\frac{21}{2}+37[/tex][tex]\frac{21+74}{2}[/tex][tex]\frac{95}{2}[/tex]

Subtract 95/2 from 55 to get the required kg.

[tex]55-\frac{95}{2}[/tex][tex]55\times\frac{2}{2}-\frac{95}{2}[/tex][tex]\frac{110-95}{2}[/tex][tex]\frac{15}{2}[/tex][tex]7\frac{1}{2}kg[/tex]

Final answer:
