Answer:
24 days
Step-by-step explanation:
The least common multiple (LCM) of 8 and 12 is 8·3 = 12·2 = 24.
The ladies will be at the nail salon on the same day again in 24 days.
_____
8 = 2³
12 = 2²·3
The LCM will have these factors to their highest powers: 2³·3 = 24.
__
The LCM is also the product divided by their greatest common factor (GCF). GCF(8, 12) = 4, so ...
LCM(8, 12) = 8·12/4 = 24
