To find the value of point R, which is two marks to the left of 1 on a number line divided into eighths, we need to determine where that position would be.
- First, note that one whole unit (1) is represented as 8/8 when divided into eighths.
- Since point R is two marks to the left of 1, we subtract 2/8 from 8/8.
So,
\[ 8/8 - 2/8 = 6/8 \]
Now we can convert \(6/8\) to its simplest form:
\[ 6/8 = 3/4 \]
Thus, point R corresponds to \(6/8\) or \(3/4\).
Now, we look for equivalent fractions for \(6/8\) among the provided options:
- \(2/8\) or \(1/4\)
- \(7/8\) or \(14/16\)
- \(6/8\) or \(3/4\) (not in the options)
- \(3/8\) or \(3/4\) (correct equivalent)
- \(1/8\) or \(2/16\)
The closest response that can match these fractions based on \(6/8\) is \(3/4\), which matches with \(6/8\) or \(3/4\).
This option, however, doesn't appear in your offered choices explicitly. Therefore, the correct pairing of fractions indicating point R as \(6/8\) or simplified \(3/4\) cannot be listed among your given options as they are perceived.
If your goal is to conceptualize, point R is located at \(6/8\) or \(3/4\). However for the multiple-choice format presented, note if specific fractions had been excluded inadvertently or transformations required to clarify options further may be initiated. Please clarify your question's context if needed.
