Vedclass · Answer

(A) proportion is a statement that two ratios are equal. To check if a proportion is correct,we simplify both sides to their lowest terms.For option $A$: $12: 9 = (12/3) : (9/3) = 4: 3$ and $16: 12 = (16/4) : (12/4) = 4: 3$. Since $4: 3 = 4: 3$,this is a correct proportion.For option $B$: $13: 11$ is already in simplest form,and $5: 4$ is also in simplest form. Since $13/11 
eq 5/4$,this is incorrect.For option $C$: $30: 45 = (30/15) : (45/15) = 2: 3$,while $13: 24$ is in simplest form. Since $2/3 
eq 13/24$,this is incorrect.For option $D$: $3: 5 
eq 2: 5$,so this is incorrect.Therefore,the correct option is $A$.

Which of the following represents a correct proportion?
