18:9 as 1:n where n is a decimal?

Answers

Answer:

18 : 9 is the same thing as 18/9.

So if we want 1 : n  = 1/n

(18 / 18) / (9 / 18)

=> 1 / 0.5

=> 1 : 0.5

Therefore, n = 0.5 is the solution of the equation.

Thanks!!

Answer:

n = 0.5

Step-by-step explanation:

To answer this question, we must first figure out the ratio 18:9.

What is 18 compared to 9?

If you said that 18 is double the amount of 9, or that 9 is half of 18, you are correct.

Using this logic, we then need to make the variable 'n' in 1:n half of 1 in decimal form.

So, what is half of 1 in decimal form?

If you said 0.5 OR 0.50, you are correct! And that is your answer !
