✔ 最佳答案
先把比例乘上佢地既最小公倍數 ->3x4x5=60咁新既比例就會係12 : 15 : 20
所以最小既一份就
=94x[12/(12+15+20)]
=24 KG

白米按1/5:1/4:1/3 之比分成三份,最少的一份應是1/5
[94 (1 / 5)] / (1/5 + 1/4 + 1/3)
= (94 / 5) / (47 / 60)
= [94(60)] / [47(5)]
= 24kg //
[94 (1 / 5)] / (1/5 + 1/4 + 1/3)
= (94 / 5) / (47 / 60)
= [94(60)] / [47(5)]
= 24kg //

94÷(1/5+1/4+1/3)×1/5
=24kg
=24kg
