Question

Compare the number of red stars to yellow stars. If the ratio remains the same, how many red stars will there be if there are 27 yellow stars?

a) 9 red stars
b) 18 red stars
c) 27 red stars
d) 36 red stars

Answer 1

To compare the number of red stars to yellow stars, we need to use proportions. Assuming a ratio of 2:3, if there are 27 yellow stars, there would be 18 red stars if the ratio remains the same.

Step-by-step explanation:

To compare the number of red stars to yellow stars, we need to know the ratio between them. Unfortunately, the ratio is not provided in the question, so we cannot determine the exact number of red stars. However, if the ratio remains the same, we can use proportions to solve the problem.

Let's assume the ratio of red stars to yellow stars is 2:3 (this is just an example, the actual ratio might be different). If there are 27 yellow stars, we can set up a proportion:

red stars / yellow stars = 2 / 3

Solving for red stars:

red stars = (2 / 3) * 27 = 18

Therefore, if the ratio remains the same, there would be 18 red stars if there are 27 yellow stars. So, the correct answer is b) 18 red stars.
