Which of the following is not a proportion?
4/5 or 8/10
18/6 or 12/4
6/16 or 3/8
27/9 or 22/4

anonymous · Answer

Hint: They are proportion if they have the same ratios 
lets use the first example, 4/5 or 8/10
I know this is proportion because 4 x 2 = 8
                                                      5 x 10 = 10
                                                      to get 8/10

anonymous · Answer

tell me when you figure out the answer

anonymous · Answer

ok

anonymous · Answer

ok my answer is 18/6 &12/4

anonymous · Answer

nope, that is not correct because 18/6 = 3    and    12/4 = 3    
  so they both have the same ratio of three.

anonymous · Answer

Omg ! okay

anonymous · Answer

now, tell me which one?

anonymous · Answer

The answer is 4/5 & 8/10

anonymous · Answer

nono.

anonymous · Answer

ok, this is probably the best way for you to understand.
Grab a calculator and type in 4/5 and 8/10 they will have the same value of 0.8 and therefore they are proportionate.

anonymous · Answer

and can you see that 8/10 simplified is 4/5, so they must have the same value and therefore are proportionate.

anonymous · Answer

You don't really need a calculator for this question, but it will assist you in your understanding and be much faster to achieving the answer, if you are allowed to use the calculator for this question.
