Question

1. if 12 out of 30 students have water bottles, to the nearest percent, what percent of the class doesnt have a water bottle? is/part = 12 of/whole = 30 % = 12/30 = x/100

Explanation:

Step1: Find the number of students without water bottles

The total number of students is \(30\), and \(12\) students have water bottles. So the number of students without water bottles is \(30 - 12=18\).

Step2: Calculate the percentage

The formula for percentage is \(\frac{\text{part}}{\text{whole}}\times100\%\). Here, the part is \(18\) (students without water bottles) and the whole is \(30\) (total students). So the percentage is \(\frac{18}{30}\times 100\%=\frac{3}{5}\times100\% = 60\%\)

Answer:

\(60\%\)
