Answer:
8
Step-by-step explanation:
Im not sure but i would go with my guts if i were you:)
7 days in a week, 3 days a rotation.
multiples of 7: 7, 14, 21, 28
multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24
the LCM is 21, because it is the smallest multiple of both numbers. there will be 21 more days until you take dance class on Mondays
54
9 x 3 = 27
27 + 27 = 54
