we obtain the ratios dividing one value by another
1.
[tex]\frac{\text{Vowels}}{\text{consonants}}[/tex]the number of vowels are 5 and the consonants are 21
so the ratio is
[tex]\frac{5}{21}\longrightarrow5\colon21[/tex]the unit ratio is
[tex]\frac{\frac{5}{21}}{1}=\frac{0.238}{1}=0.238[/tex]2.
to determine if two ratios are equivalent we must simplify the fractions
[tex]\frac{12}{16}=\frac{6}{8}=\frac{3}{4}[/tex][tex]\frac{72}{96}=\frac{36}{48}=\frac{18}{24}=\frac{9}{12}=\frac{3}{4}[/tex]the ratios are equivalent because the two represent 3/4
the unit ratio of 3/4 is
[tex]\frac{\frac{3}{4}}{1}=\frac{0.75}{1}=0.75[/tex]
