Answer 2

What is the rational number equivalent to 3 point 12 with a bar over 12?

3 and 4 over 33
3 and 8 over 33
3 and 10 over 39
3 and 5 over 39

Answer 3

Let
x = 3.12121212121212....

notice how the 12 portion repeats itself forever

Answer 4

if we were to multiply both sides by 100, then we'd have

x = 3.12121212121212....
100x = 312.121212121212....

the decimal point will move 2 spots over to the right

Answer 5

now subtract x and 100x
