Question

9/4

Answer 1

To determine which ratio forms a proportion with 9/4, we can set up and solve the following equation:

x/1 = 9/4

We can cross multiply:

4x = 9(1)

4x = 9

To solve for x, we divide both sides of the equation by 4:

x = 9/4

Therefore, the ratio 9/4 forms a proportion with itself.
