I need to answer this correctly!!

Question

6/9 is a rational number. Select all the rational numbers that are equivalent to 6/9.

 

- 2/3

- 0.6666666... (One six with a bar over it)

- 0.6666666... (two sixes with a bar over both sixes)

- 0.666666666667 (two sixes and a seven at the end, bar over both sixes)

Answer 1

For this question, you need to look up the definition of Ration Numbers. A Rational Number is any number that can be written as a fraction. So, right off the bat you know 2/3 is a possible answer.

 

Can B, C, or D also be an answer? 

If you put 2/3 into decimal form, you get 0.666667 and the 7 only shows up cause your screen can't be any longer (you'd actually have a bar over the 6's) So we know answer D is also possible.

 

Thus, A and D are probable answers
