Answer:
C
Step-by-step explanation:
4.32/5=0.86 per bar
6.48/8=0.81 per bar <---- better buy
62 is 50% of 124 (62*2=124)
Step-by-step explanation:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
56 = 2 ×2 × 2 × 7
Now
Common factor = 2
Remaining factor = 2 × 3 × 2 × 3 × 7
LCM = RF × CF
= 504
hence the lCM of 12 , 18 and 56 is 504...
