Answer:

A. 4/20 and 1/5.

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.

Ans.: A.

Answer:

A

Explanation:


(4)/(20) ← divide numerator/ denominator by 4

=
(1)/(5)

Thus A form a proportion


(4)/(20)
(2)/(5)

Thus B is not a proportion


(20)/(4) ← divide numerator/ denominator by 4

=
(5)/(1)
(1)/(5)

Thus C is not a proportion


(20)/(4)
(2)/(5)

Thus D is not a proportion
