Answer:
A
Step-by-step explanation:
[tex]\frac{4}{20}[/tex] ← divide numerator/ denominator by 4
= [tex]\frac{1}{5}[/tex]
Thus A form a proportion
[tex]\frac{4}{20}[/tex] ≠ [tex]\frac{2}{5}[/tex]
Thus B is not a proportion
[tex]\frac{20}{4}[/tex] ← divide numerator/ denominator by 4
= [tex]\frac{5}{1}[/tex] ≠ [tex]\frac{1}{5}[/tex]
Thus C is not a proportion
[tex]\frac{20}{4}[/tex] ≠ [tex]\frac{2}{5}[/tex]
Thus D is not a proportion
Answer:
A. 4/20 and 1/5.
Step-by-step explanation:
If we divide 4/20 we get 1/5. So there is two ratio in the A. Which is 1/5 and 1/5, so there is a proportion.
For B: If we divide 4/20, we get 1/5. But there is another ratio which is 2/5. So got no proportion there.
For C: If we divide 20/4, we get 5. But there is also no proportion between them.
For D: If we divide 20/4, we get 5. But there is no proportion between 5 and 2/5.
So finally we get that there is proportion between 4/20= 1/5 and 1/5. Which is A.
