Given:
Number of white roses = 4
Number of red roses = 8
To find:
The ratio of the number of red roses to the number of white roses.
Solution:
Using the given information, the ratio of the number of red roses to the number of white roses is
[tex]\text{Required ratio}=\dfrac{\text{Number of red roses}}{\text{Number of white roses}}[/tex]
[tex]\text{Required ratio}=\dfrac{8}{4}[/tex]
[tex]\text{Required ratio}=\dfrac{2}{1}[/tex]
[tex]\text{Required ratio}=2:1[/tex]
Therefore, the required ratio is 2:1.
