I can't figure this one out.

Write the decilam equivalent, using the bar notation
7/18

Now, here are my choices for answers, and I do not come up with any of them

A. 0.6 (line over .6)
B. 0.16 (line over .6)
C. 0.61 (line over .61)
D. 0.61

2 answers

7/18 = .3888...
or .38 with a bar over the 8 to show the 8 is repeating

none of your choices match that.
either:
1. you made an error in your typing, or
2. "they" are wrong.
That's what I came up with also.
My instructor seems to have a lot of "mistakes" when giving us multiple choice answers.
I guess I will just show what I got and go from there.
Thanks
