THANKYOU
homework please answer
30 - 27 = 3
3/30 = 0.1
0.1 * 100 = 10%
To find the percentage of students who do not have a mobile phone, follow these steps:
Step 1: Subtract the number of students who have a mobile phone from the total number of students.
Here, the total number of students is 30, and the number of students who have a mobile phone is 27.
So, the number of students who do not have a mobile phone is 30 - 27 = 3.
Step 2: Convert the number of students who do not have a mobile phone into a percentage.
To do this, divide the number of students who do not have a mobile phone by the total number of students (30) and multiply by 100.
(3 / 30) * 100 = 0.1 * 100 = 10
Therefore, 10% of the students do not have a mobile phone.
