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?
Balaich = 1 ph脿irt = \(50\) sgoilear
Nigheanan = 3 p脿irtean = \(3 \times 50 = 150\) sgoilear
Bha \(150\) nighean aig an diosgo.
Tha an co-mheas eadar nigheanan agus balaich aig f猫ill-reic na sgoile aig \(1 : 2\).
Ma bha \(20\) balach ann, cia mheud nighean a bh' aig an fh猫ill?
Balaich = 2 ph脿irt = \(20\) sgoilear, mar sin 1 ph脿irt = \(10\) sgoilear.
Nigheanan = 1 ph脿irt = \(10\) sgoilear.
Bha \(10\) nighean aig an fh猫ill.
