Answer:

Well, I'm not really sure what to do, but if you just need the numbers to multiply to get the latter numbers in the question they are: 10/11 (for the first question) and 81/80 for the second.

Step-by-step explanation:

For Question #1: You just multiply 5/11 by two to get the number that 1/2 has to multiply to get 5/11. And 5/11 * 2 is 10/11. So I guess the answer is 10/11...

For Question #2: The common denominator for them both is 180, and 4/9 times 81/ 80 is what 80/180 (4/9) has to multiply by to get 81/180.

I used the equation 4/9x=9/20

Multiplied the 9 and then divided by 4 to get the answer, which was 81/80.

***I also noticed, that 1/2 is 1/22 away from 5/11, and 4/9 is 1/180 away from 9/20.

Hope this helps!
