Eisimpleir
Tha Tom ag iarraidh Tbh a cheannach le aonta creideis. Feumaidh e aon ch貌igeamh dhen phr矛s iomlan de \(\pounds200\) a ph脿igheadh mar 脿irleas.
D猫 an t-脿irleas a ph脿igheas e?
Freagairt
脌irleas \(= \frac{1}{5}\) de \(\pounds200\)
\(= \frac{200}{5}\)
\(= \pounds40\)
Feumaidh Tom 脿irleas de \(\pounds40\) a ph脿igheadh.
Obraich a-nis a-mach an t-脿irleas anns gach suidheachadh a leanas.
Question
D猫 na bhios ann an 脿irleas \(15\%\) de \(\pounds300\)?
脌irleas \(= 15\%\) de \(\pounds30\)
\(= 15 \times 1\%\) de \(\pounds300\)
\(= 15 \times 3\)
\(= \pounds45\)
'S e an t-脿irleas \(\pounds45\)
Question
D猫 na bhios ann an 脿irleas \(\frac{1}{4}\) de \(\pounds300\)?
脌irleas \(= \frac{1}{4}\) de \(\pounds300\)
\(= \frac{{300}}{4}\)
\(= \pounds75\)
'S e an t-脿irleas \(\pounds75\).
Question
D猫 na bhios ann an 脿irleas \(20\%\) de \(\pounds500\)?
脌irleas \(= 20\%\) de \(\pounds500\)
\(= \frac{{500}}{5}\) (oir tha \(20\%\) co-ionann ri \(\frac{1}{5}\))
\(= \pounds100\)
'S e an t-脿irleas \(\pounds100\).
