Answer:
Average mean of the fractions is [tex]1\frac{63}{80}[/tex].
Step-by-step explanation:
We have to find the average mean of the given fractions
[tex]\frac{2}{4}, \frac{18}{5}, \frac{28}{10}, \frac{5}{20}[/tex]
Since mean of numbers is represented by the expression
Mean = [tex]\frac{\text{Sum of fractions}}{\text{Number of fractions}}[/tex]
= [tex]\frac{\frac{2}{4}+\frac{18}{5}+\frac{28}{10}+\frac{5}{20}}{4}[/tex]
= [tex]\frac{\frac{1}{2}+\frac{18}{5}+\frac{14}{5}+\frac{1}{4}}{4}[/tex]
= [tex]\frac{\frac{10+72+56+5}{20}}{4}[/tex]
= [tex]\frac{143}{80}[/tex]
= [tex]1\frac{63}{80}[/tex]
Therefore, average mean of the fractions is [tex]1\frac{63}{80}[/tex].
