ANSWER
65
EXPLANATION
This will form a sequence with first term:
![a_{1} = 102](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%20102)
with constant difference d=6 and last term
![l = 486](https://tex.z-dn.net/?f=l%20%3D%20486)
The last term is a term in the sequence, therefore;
![l=a_1+d(n-1)](https://tex.z-dn.net/?f=l%3Da_1%2Bd%28n-1%29)
![486=102+6(n-1)](https://tex.z-dn.net/?f=486%3D102%2B6%28n-1%29)
![486 - 102 = 6(n-1)](https://tex.z-dn.net/?f=486%20-%20102%20%3D%206%28n-1%29)
Simplify the LHS
![384= 6(n-1)](https://tex.z-dn.net/?f=384%3D%206%28n-1%29)
Divide both sides by 6.
![64=n-1](https://tex.z-dn.net/?f=64%3Dn-1)
![64 + 1 = n](https://tex.z-dn.net/?f=64%20%2B%201%20%3D%20n)
Therefore
![n = 65](https://tex.z-dn.net/?f=n%20%3D%2065)
Hence there are 65 multiples of 6.

102% as a fraction would be 102/100, because a percent is by the one hundreds, and you can have a fraction be by hundreds. You can reduce the fraction by dividing it by 2, which equals 51/50. Another example, to clarify, is to make 41% a fraction, and decimal. Once again a percent is base 100, so the fraction would be 41/100, then to make it a decimal, you would put a decimal point in front of the 41, to make it .41. Hope I helped, and if you don't understand, tell me and I will try to make it better.
Answer:
1: proportional
2: non-proportional
3: non-proportional
4: non-proportional
5: proportional
6: proportional
7: non-proportional
8: proportional
9. proportional.
10. proportional.
11. non-proportional.
12. proportional.
Step-by-step explanation:
I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.
