Turn triple ratio into percent

Question

I have this triple ratio:

14:7:5

How would one go about turning this into a percentage i.e something to the likes of this

30%

20%

50%

Answer 1

Divide by the total: $14 + 7 + 5 = 26$.

$$\frac{14}{26} = 0.538 = 53.8\%,$$ $$\frac{7}{26} = 0.269 = 26.9\%,$$ $$\frac{5}{26}= 0.192 = 19.2\%.$$

(N.B. All decimals and percentages rounded to 3 significant figures for simplicity.)
