Given data,
[tex]-5\frac{1}{2},\text{ 3.75,-20.8,-4,11.25}[/tex]For the greatest sum,
We need to add the two large number.
Thus,
[tex]11.25+3.75=15[/tex]For the greatest difference, we need to substract the largest number from the smallest,
Thus,
[tex]11.25-(-20.8)=32.05[/tex]To find the greatest product,
we should multiply the two great numbers.
[tex]11.25\times3.75=42.1875[/tex]To find the greatest quotient,
we need to divide the largerst number by the smallest
[tex]\frac{11.25}{3.75}=3[/tex]
