If you add all of the digits of a number, and it's divisible by 3, the entire number will be divisible by 3. If the number is divisible by 2 and 3, it's divisible by 6 as well. If the digits of a number add up to a number divisible by 9, the whole number will be divisible by 9.

Answer:

Number of Flowering Plants = 30

Number of vegetable plants = 20

Step-by-step explanation:

Im assuming the question is asking for the number of vegetables and number of flowers.

We need to convert 60% and 40% to decimal. The process is dividing by 100. Hence,

60% = 60/100 = 0.6

and

40% = 40/100 = 0.4

We multiply these with the total number to get number of vegetable and flowering plants.

So,

Number of Flowering Plants = 0.6 * 50 = 30

Number of vegetable plants = 0.4 * 50 = 20
