It would be 1 4/8 or 1 ½ if simplified
Since there is 8 parts in between 1 and 2 on the number line the denominator is 8.
The most frequent measurement is right in the middle, which if you count to that line you can see it goes up to 4 parts.
And because it’s already past the whole number 1 it would be 1 4/8 or 1 ½
I hope this helps and is understandable!
