Answer explanation

Choice B is correct. If 1,200 customers register for new accounts every day, then (1,200)(5) = 6,000 customers registered for new accounts in the first 5 days. Therefore, of the first 60,000 new accounts that were registered, the fraction 6,000 over 60,000, or the fraction 1 over 10, were registered in the first 5 days.

Choice A is incorrect. The fraction one fifth represents the fraction of accounts registered in 1 of the first 5 days. Choice C is incorrect and may result from conceptual or computation errors. Choice D is incorrect. The fraction 1 over 50 represents the fraction of the first 60,000 accounts that were registered in 1 day.
