Answer:
[tex]\sf (a) \ Archery\\ \\ \\(b) \ \dfrac{7}{20} \\ \\ \\(c) \ \dfrac{3}{20}[/tex]
Explanation:
Part (A)
Convert them to decimals:
As 0.6 > 0.25, we can determine that archery got more of the votes.
Part (B)
To find the difference between fractions, simply subtract.
[tex]\rightarrow \sf \dfrac{3}{5} - \dfrac{1}{4}[/tex]
[tex]\rightarrow \sf \dfrac{4(3)}{20} - \dfrac{5(1)}{20}[/tex]
[tex]\rightarrow \sf \dfrac{12-5}{20}[/tex]
[tex]\rightarrow \sf \dfrac{7}{20}[/tex]
Part (C)
Subtract the addition of those who chose any of the sports from 1
[tex]\rightarrow \sf 1- \dfrac{3}{5} - \dfrac{1}{4}[/tex]
[tex]\rightarrow \sf \dfrac{20}{20} - \dfrac{12}{20} - \dfrac{5}{20}[/tex]
[tex]\rightarrow \sf \dfrac{20-12-5}{20}[/tex]
[tex]\rightarrow \sf \dfrac{3}{20}[/tex]
