PARCC Averages and Rounding Practice Questions
1. The average of six numbers is 4. If the average of two of those numbers is 2, what is the average of the other four numbers?
1. A: A set of six numbers with an average of 4 must have a collective sum of 24. The two numbers that average 2 will add up to 4, so the remaining numbers must add up to 20. The average of these four numbers can be calculated: 20/4 = 5.
