Answer 2

The other number is 22.5.

Step-by-step explanation:

Since we have given that

Ratio of two numbers be 8:9

Let the first number be 8x.

Let the second number be 9x.

According to question, if the first number is 20.

So, it becomes,

$8x=20\\\\x=\dfrac{20}{8}\\\\x=2.5$

So, the other number would be

$9x=9\times 2.5=22.5$

Hence, the other number is 22.5.
