That's a statement. There's no question there.
All we can tell about the 6 numbers is that they add up to 126 .
6 + 7 + 8 = 21 there are three numbers so divide by three 21/3 = 7
5 or 6. If you want average its 5.5
Add the numbers together, then divide the result by the number of numbers that were added. For example, 4, 6, 9, and 2 = 21. Now divide 21 by 4 to get the average, which is 5.25.
-21
The sum of the six numbers/6 = 12 The sum of the six numbers = 72 (72-6)/6=11
6+8+7= 21 21/3 = 7 The average is 7.
add all three number together and then divide by three (because there's three numbers) 21+6=27, 27+9=36, 36/3=12 12 is the answer.
2
144
19 + 24 + 20 = 63/3 = 21 The average of the three numbers is 21.
The average of several numbers is the sum of the numbers divided by the quantity of the numbers. (3 + 3.5 + 6) ÷ 3 = 4 1/6
The least common multiple of the numbers 21 and 6 is 42.
