The ratio is given by
[tex]\text{ the ratio of red roses to white roses = }\frac{\text{ the number of red roses}}{\text{ the number of white roses}}[/tex]the number of red roses = 24
the number of white roses = 9
Therefore,
[tex]\text{ the ratio of red roses to white roses = }\frac{24}{9}=\frac{\frac{24}{3}}{\frac{9}{3}}=\frac{8}{3}=8\colon3[/tex]Hence, the ratio of the red roses to the white roses is 8:3
