The greatest common factor (GCF) of 12, 18, and 26 is: 2
Since the lowest number is 12, you should only include factors up to 12.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 18: 1, 2, 3, 6, 9
Factors of 26: 1, 2
The common factors between the three numbers are 1 and 2, but you are looking for the greatest common factor. The greatest means the highest, and which is the highest number out of 1 and 2? 2, so that is your answer.
Average rate of change is the same as finding slope between a line on a non- linear function.
Using the ordered pairs
(5,10) and (8,1)
(10-1)/(5-8) = 9/-2 = -9/2
4 units = blue
1 unit = yellow
total: 5 units = 40
1 unit = 40 ÷ 5 = 8
yellow: 8
blue: 8×4 = 32
13/12 is the answer in simplest fraction form.
16=4 because in order to get 4 you need have to divide 16 into 4
