3. 21:5 or  

\frac{21}{5} or

4.2 as a decimal

4. 5:21 or  

\frac{5}{21} or

0.24 as a decimal

Step-by-step explanation:

A ratio is a comparison of two quantities and can be written in several forms including fractions. It is most commonly written in fraction form or a:b.  

To write a ratio, we count the number of each quantity we are comparing. A part to whole ratio for letters and vowels would be the part compared to the whole. For example, there are 21 consonants to 26 letters in the alphabet. We write 21:26 or \frac{21}{26} or 0.81. We can also compare the number of vowels which is 5:26 or

A part to part ration compares a part to a part like the number of consonants is 21 with the number of vowels is 5. We write the ratio as consonants : vowels.  

21:5 or  

\frac{21}{5} or

4.2 as a decimal.  

We can reverse and write vowels : consonants.

5:21 or  

\frac{5}{21} or

0.24 as a decimal.
