The students saw 9 perennial flowers and 81 annual flowers. what percentage of the flowers were perennials?

Total number of flowers: 81 + 9 = 90

So

81/90 × 100

0.9 × 100

90

So there are 90% Perennials

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
