A' cleachdadh co-mheas

Eisimpleir

Tha an co-mheas eadar nigheanan agus balaich aig diosgo na sgoile aig \(3 : 1\).

Ma bha \(50\) balach ann, cia mheud nighean a bh' aig an diosgo?

Freagairt

Balaich = 1 ph脿irt = \(50\) sgoilear

Nigheanan = 3 p脿irtean = \(3 \times 50 = 150\) sgoilear

Bha \(150\) nighean aig an diosgo.
