Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.

Let the number of tulips and roses are 2x and x respectively.
According to the question,


Divide both sides by 3.


Now,
Number of tulips 

Therefore, the number of tulips is 12.
It’s 663.48 because if you divide 276.45 by 5 than you get 55.19 and multiply that by 12 and it’s 663.48
The point would be on the -2.
