Question 1 Report
The pie chart shows how \(600\) students travel to school. \(35\%\) of the students walk.
Work out the number of students who walk.
Answer Details
Finding a percentage of an amount means finding that many hundredths of it. Here you need \(35\%\) of the \(600\) students shown by the whole pie chart.
\[ 35\% \text{ of } 600 = \frac{35}{100}\times 600 = 0.35\times 600 \] \[ 0.35\times 600 = 210 \]A useful check without a calculator: \(10\%\) of \(600\) is \(60\), so \(30\%\) is \(180\); \(5\%\) is half of \(10\%\), which is \(30\); and \(180+30=210\).
So \(210\) students walk to school [B1]
The pie chart itself is not needed for this part, because the percentage is given in words. Do not try to measure the sector angle; use the stated \(35\%\) and the stated total of \(600\).
