Ciamar a gheibh sinn \(\frac{3}{5}\,de\,20\)
Obraich a-mach \(\frac{1}{5}\,de\,20\), agus an uair sin iomadaich le \(3\).
\(\frac{1}{5}\,de\,20 = 20 \div 5 = 4\)
Tha sinn ag iarraidh \(\frac{3}{5}\,de\,20\), agus mar sin bidh sinn ag iomadachadh \(4\) le \(3\).
\(\frac{3}{5}\,de\,20 = 4 \times 3 = 12\)
Iomadaich \(\frac{3}{5}\) le \(20\).
\(\frac{3}{5} \times 20 = \frac{3}{5} \times \frac{{20}}{1} = \frac{{60}}{5} = 12\)
Cleachd d貌igh sam bith agus lorg \(\frac{3}{7}\,de\,35\).
'S e am freagairt \(15\).
A' cleachdadh D貌igh-obrach 1: \(\frac{1}{7}\,de\,35 = 5\), agus \(3 \times 5 = 15\).
