Paul is 14 years old. His sister is exactly 6 years younger, so this year she is 8 years old.
This year, the ratio of Paul’s age to his sister’s age is 14 : 8

14 : 8 written as simply as possible is 7 : 4

When Paul is 21, what will be the ratio of Paul’s age to his sister’s age?
Write the ratio as simply as possible.

ratio = 21:15

Step-by-step explanation:

Paul's sister is 6 years younger than Paul so that means if Paul is 21, 21 - 6 = 15. Your new ratio would be 21:15

21:15 written as simply as possible is 10.5:7.5 or 11:8

I'm sorry if you get it wrong :(

(x^2-9)/ (x + 3) = x-3
