Tha \(3\) cait agus \(7\) coin aig tuathanach.
Sgrìobh co-mheas nan cat ri coin agus co-mheas nan con ri cait.
Cait : Coin = \(3 : 7\)
Coin : Cait = \(7 : 3\)
Tha \(85\) caoraich agus \(15\) mart cuideachd aig an tuathanach.
Sgrìobh co-mheas nam mart ri caoraich san riochd as sìmplidhe.
mart : caoraich = \(15 : 85\)
Gabhaidh \(15\) agus \(85\) a roinn le \(5\)
\(\frac{{15}}{5} = 3\)
\(\frac{{85}}{5} = 17\)
Mar sin \(15 : 85 = 3 : 17\)
