Answer 2

Percentage of Perennial flowers

Step-by-step explanation:

• A simple formula can be used to change number of flowers into percentage, i.e.
• Formula:     No. of flowers (perennial) / Total no. of flowers X 100

Step 1:

Lets see the no. of perennial flowers = 30

Lets see the total no. of flowers altogether = 40

Step 2: Apply formula

   30/40 X 100

= 0.75 X 100

= 75 %

• Tip: In order to change any number into percentage, you simply multiply it by 100.
