Tha e furasta cuid de cheudadan atharrachadh gu bloighean agus obrachadh a-mach nas luaithe mar sin. Mar eisimpleir:
\(50\% = \frac{{50}}{{100}} = \frac{1}{2}\)
\(25\%=\frac{25}{100}=\frac{1}{4}\)
\(75\%=\frac{75}{100}=\frac{3}{4}\)
\(20\%=\frac{1}{5}\)
Feuch a-nis na ceistean gu h-矛osal.
Obraich a-mach \(50\%\) de \(\pounds400\).
\(50\% \,de\,\pounds400\)
\(= \frac{1}{2} \times 400\)
\(= \pounds200\)
Tha \(20\%\) dhe na \(225\) sgoilearan ann an 脌S4 ann an sgoil a' gabhail bus na sgoile dhachaigh.
Cia mheud sgoilear a bhios a' gabhail bus na sgoile?
\(20\% = \frac{{20}}{{100}} = \frac{1}{5}\)
Mar sin \(20\%~de~225\)
\(= 45\).
Bidh \(45\) sgoilearan a' gabhail bus na sgoile.
