Pour trouver les fractions équivalentes nécessaires pour créer les dénominateurs communs, il existe un moyen rapide de trouver le nombre dont nous avons besoin pour multiplier à la fois le numérateur et le dénominateur.

Baada ya kupata denominator ya kawaida ya sehemu mbili, tunabadilisha sehemu ndogo kwa sehemu sawa na LCD. Wakati wa kutafuta sehemu sawa zinazohitajika ili kuunda denominators ya kawaida, kuna njia ya haraka ya kupata nambari tunayohitaji kuzidisha nambari zote na denominator.
