Antwoord: #1/6+1/5+1/3 = 7/10# Uitleg: We moeten elk van de termen omzetten zodat ze dezelfde noemer hebben. De kleinste gemene deler is #30# # 1/6 = 5 / 30color (wit) ("XXX") 1/5 = 6 / 30color (wit) ("XXX") 1/3 = 10/30 # Zo #1/6+1/5+1/3# #color (wit) ("XXX") = 30/05 + 30/06 + 10/30 # #color (wit) ("XXX") = (5 + 6 + 10) / 30 # #color (wit) ("XXX") = 21/30 # #color (wit) ("XXX") = 7/10 #
