The Commutative Property of Addition
Step-by-step explanation:
They have a common denominator of 12
21/12+6/12+20/12+4/12+3/12+6/12=60/12=5 cups
or you could group ingredients with the same denominators
7/4+1/4+1/2+1/2+5/3+1/3=
8/4+2/2+6/3=
2+1+2=5
The Commutative Property of Addition says the order of the numbers doesn’t change the outcome.
If you are just dividing percent's, then each grade would have 12.5 percent.
Formula for finding mean:
Mean = (a1 + a2 + ... + an) / n
Mean is another word for average; average number of a data set.
Problems with steps:
---------------------------------------------------------------------------------------
1) 9, 3, 6
Average = Sum/Count
Sum = 18/6
Count = 3
2) 14, 12, 17, 9
52/4
Mean = 13
3) 15,8,10,5,7
= 45/5
Mean = 9
4) 18,19,11
= 48/3
Mean = 16
5) 4,20,16,4
= 44/4
Mean = 11
6) 12,11,12,20,15
= 70/5
Mean= 14
7) 19,8,3
= 30/3
Mean = 10
8) 7,13,6,2
= 28/4
Mean = 7
9) 12,15,17,2,14
60/5
Mean = 12
10) 10,18,8
= 36/3
Mean = 12
11) 5,2 ,0,1
= 8/4
= 2
12) 3,9,5,16,7
= 40/5
Mean = 8
