Explanation:

Step1: Simplify ratios

For $60:10$, divide both by 10, we get $\frac{60}{10}:\frac{10}{10}=6:1$.
For $40:20$, divide both by 20, we get $\frac{40}{20}:\frac{20}{20}=2:1$.
For $75:55$, divide both by 5, we get $\frac{75}{5}:\frac{55}{5}=15:11$.
For $10:30$, divide both by 10, we get $\frac{10}{10}:\frac{30}{10}=1:3$.
For $84:7$, divide both by 7, we get $\frac{84}{7}:\frac{7}{7}=12:1$.
For $12:108$, divide both by 12, we get $\frac{12}{12}:\frac{108}{12}=1:9$.
For $24:28$, divide both by 4, we get $\frac{24}{4}:\frac{28}{4}=6:7$.
For $44:33$, divide both by 11, we get $\frac{44}{11}:\frac{33}{11}=4:3$.
For $250:400$, divide both by 50, we get $\frac{250}{50}:\frac{400}{50}=5:8$.
For $270:30$, divide both by 30, we get $\frac{270}{30}:\frac{30}{30}=9:1$.
For $63:33$, divide both by 3, we get $\frac{63}{3}:\frac{33}{3}=21:11$.
For $32:18$, divide both by 2, we get $\frac{32}{2}:\frac{18}{2}=16:9$.
For $4:80$, divide both by 4, we get $\frac{4}{4}:\frac{80}{4}=1:20$.
For $55:33$, divide both by 11, we get $\frac{55}{11}:\frac{33}{11}=5:3$.
For $1000:100$, divide both by 100, we get $\frac{1000}{100}:\frac{100}{100}=10:1$.
For $20:340$, divide both by 20, we get $\frac{20}{20}:\frac{340}{20}=1:17$.

Answer:

The simplified ratios are as calculated above for each pair of numbers.
