for a class of 24,78% of students got a B or better on the tex How many students is this? Round to a wholenumber
natita [175]

Step 1

Use the ratio of the number to the percentage to get the required answer.

\frac{Total\text{ number of students}}{\text{The required number of students}}=\frac{Total\text{ percentage of the class}}{\text{Given percentage}}

Where,

\begin{gathered} \text{The total number of students = 24} \\ \text{The required number }of\text{ students= x} \\ \text{The total percentage of the class = 100} \\ \text{Given percentage = 78} \end{gathered}

Step 2

Get the required answer

\begin{gathered} \frac{24}{x}=\frac{100}{78} \\ 100x=24\times78 \\ 100x=1872 \\ \frac{100x}{100}=\frac{1872}{100} \\ x=\text{ 18.72} \\ \text{Hence} \\ x\approx19students\text{ rounded to a whole number } \end{gathered}

The number of students that got B or a better grade on the test = 19 students rounded to a whole number.
