La oss prøve å skrive 1,501 som prosent.

Vi vil skrive det som et tall over 100.

Dette er det samme som 1,501 over 1.

Vi har ikke endret verdien,
og multipliserer med 100 over 100.

Når vi gjør dette produktet
uten å endre verdien,

multipliserer vi bare med 1.

Men vi endrer måten vi fremstiller det.

Nevneren er 1 ganger 100.

Det blir 100.

Vi multipliserer 1,501
med 100 for å finne telleren.

Da blir dette,

om vi multipliserer det med 10,

flytter vi desimalen en plass,

og vi vil multiplisere med 100,

vi vil multiplisere med 10 igjen.

Vi flytter dseimalen to plasser til høyre.

Vi multipliserer det med 10 to ganger.

Eller med 100.

Vi multipliserer med 10,

her multipliserer vi med 100.

Desimalene vil stå her nå.

Vi får 150,1.

Vi har omskrevet 1,501
som 150,1 over 100,

eller 150,1 av 100.

La meg skriver 150,1 av 100,

som er det samme som 150,1 prosent.

Det er det samme som 150,1%.

Da er vi ferdige.

Det vi egentlig gjør,

om du vil forenkle proseesen,

er å multiplisere med 100
for å få 150,1,

og da sier vi at det er prosenten.

Så husk å skrive symbolet %.
