The ratio of carrot plants to potato plants in the garden is 2: 5. if the garden has 35 potato plants, how many carrot plants does it have?

number of carrot plants = 14 carrot plants

Explanation:
The ratio between carrots to potatoes is given as 2:5 and the number of potatoes is given as 35 potato plants.
To get the number of carrot plants, we would simply use cross multiplication as follows:
carrots : potatoes
2          :   5
??        : 35
Number of carrot plants = (35*2) / 5 = 14 carrot plants

Hope this helps :)
