Answer: On Tuesday, Marietta sold more part of boxes of cheese.
Step-by-step explanation:
Since we have given that
Part of boxes of cheese Marietta sold on Monday is given by
[tex]\frac{7}{9}[/tex]
Part of boxes of cheese Marietta sold on Tuesday is given by
[tex]0.85=\frac{85}{100}=\frac{17}{20}[/tex]
Now, to compare the both the part of cheese, we need to make the denominator same ,
L.C.M. of 9 and 20 = 180
So, it becomes,
[tex]\frac{7\times 20}{9\times 20}=\frac{140}{180}[/tex]
Similarly,
[tex]\frac{17\times 9}{20\times 9}=\frac{153}{180}[/tex]
Hence, On Tuesday, Marietta sold more part of boxes of cheese.
