Subtraktion af blandede tal: 7 6/9 - 3 2/5

Vi kan trække to blandede tal fra hinanden ved først at omskrive dem til uægte brøker. Dette gøres ved at gange det hele tal med nævneren og dernæst lægge dette tal til i tælleren. Dernæst skal brøkerne omskrives så de har fællesnævner. Nu kan brøkerne trækkes fra hinanden. Til sidst skal du omskrive den resulterende uægte brøk til et blandet tal. Lavet af Sal Khan.
