A' coimeas pr矛sean an aonaid
Gl猫 thric bidh bathar ann am pacaidean de dhiofar meudan is phr矛sean. Tha e feumail pr矛s an aonaid a choimeas mus co-dh霉in thu d猫 am meud pacaid a cheannaicheas tu.
Eisimpleir
Tha gr脿n bracaist ann am pacaidean de thr矛 meudan.
D猫 a' phacaid sa bheil an luach airgid as fhe脿rr?
Freagairt
Cosgais aonaid pacaid bheag \(= 205\) sgillinn \(\div 250 = 0.82\) sgillinn gach gram
Cosgais aonaid pacaid mheadhain \(= 285 \div 375 = 0.76\) sgillinn gach gram
Cosgais aonaid pacaid mh貌r \( = 315 \div 500 = 0.63\) sgillinn gach gram
'S e a' phacaid mh貌r as saoire gach gram, agus mar sin seo an luach as fhe脿rr.
Question
D猫 an tiona as fhe脿rr luach?
Cosgais aonaid tiona beag \(= \pounds7.60 \div 1 = \pounds7.60\) gach liotair
Cosgais aonaid tiona meadhanach \(= \pounds15.80 \div 2.5 = \pounds6.32\) gach liotair
Cosgais aonaid tiona m貌r \(= \pounds26.50 \div 5 = \pounds5.30\) gach liotair
'S e an tiona m貌r as saoire gach liotair, agus mar sin 's e as fhe脿rr luach.
