Step-by-step explanation:

Basically adding 4 to both numerator and denominator successively - (x+4)/(y+4)

20+4/22+4 = 24/26

Answer:

these pairs represent proportional relationships.

Step-by-step explanation:

The ratios that are provided are 16:18, 20:22, 8:10, 12:14, and 4:6. Let's investigate if the links between these pairings are proportionate.

The values for one quantity in a proportional relationship are obtained by multiplying each value by the same number. In particular, the connection between two quantities, A and B, is proportional if and only if:

A/B = Constant

Let's now examine each of the provided ratios:

1. 4:6:

  • The ratio simplifies to 2:3.
  • The constant ratio is 2/3.

2. 8:10:

  • The ratio simplifies to 4:5.
  • The constant ratio is 4/5.

3. 12:14:

  • The ratio simplifies to 6:7.
  • The constant ratio is 6/7.

4. 16:18:

  • The ratio simplifies to 8:9.
  • The constant ratio is 8/9.

5. 20:22:

  • The ratio simplifies to 10:11.
  • The constant ratio is 10/11.

These pairings show proportional connections since every simplified ratio has the same constant value.
