Final answer:
When solving the expression 60 ÷ 660 ÷ 6, we get approximately 0.015. This means we can solve the problem related to the number of bike racks in option B.
Step-by-step explanation:
When solving the expression 60 ÷ 660 ÷ 6, we divide 60 by 660 first. This gives us 0.0909 (repeating). Then, we divide the result by 6, which gives us 0.01515 (repeating). So, the answer is approximately 0.015.
This means that we can solve the problem related to the number of bike racks in option B) There are 60 bikes parked in the bike racks at Billy's school. If there are 666 bikes parked at each bike rack, how many bike racks are there?
Since each bike rack can hold 666 bikes, we divide the total number of bikes (60) by the number of bikes per rack (666). This gives us 0.09009 (repeating), which represents the decimal portion of the number of bike racks. So, there would be approximately 0 bike racks.
