Practice questions
Challenge questions
Build a percentage that cannot be found in a single step — e.g. 37%, 48%
Word problems
Real-life contexts — read carefully and identify the calculation needed
Mental methods
Build from 10%: \(10\%=\div10\) · \(5\%=\tfrac{1}{2}\) of \(10\%\) · \(1\%=\div100\)
Examples: \(35\%\) of \(£80\): find \(10\%=£8\), \(5\%=£4\), so \(35\%=3\times£8+£4=£28\)
Other shortcuts: \(50\%=\div2\) · \(25\%=\div4\) · \(75\%=\tfrac{3}{4}\)
