Question

70% of 25 students are good in mathematics. How many are not good in mathematics.
I will give barainlest tag to the best answer please help​

Answer 1

percentage of students good at math = 75%

percentage of students not good at math = (100-70)%

= 30%

let the number of students not good at math be x

percentage = number of students not good at math/total students × 100

30 = x/25 × 100

30 = x × 4

30/4 = x

= 7.5

OR YOU CAN ALSO DO IT LIKE THIS

(100-70)% of 25

30% of 25

30/100 × 25

7.5
