It is given that, Mrs. Jones bought three 2-kilogram packages of flour.
And
[tex] 1 kilogram = 1000 grams [/tex]
And three 2 -kilogram packages means she bought 6 kilogram flour .
So we need to convert 6 kilogram flour into grams.
If,
[tex] 1 kilogram = 1000grams,
\\
than,
\\
6 kilograms = 6*1000=6000 grams
[/tex]
So she bought 6000 grams of flour .
