Answer: The ratio of the number of cabbages to the number of cauliflowers that Sheena buys can be written as:
630:270
To simplify this ratio, we can divide both terms by their greatest common factor, which is 90.
Dividing both terms by 90, we get:
630/90 : 270/90
Simplifying, we get:
7:3
Therefore, the ratio of the number of cabbages to the number of cauliflowers that Sheena buys is 7:3.
