The line of a number line goes in order like 0 1/4 1/2 then blank 1 what is the missing fraction
The patttern here is adding 1/4 to each number.
Your number line's order is...
0, 1/4, 1/2, __, 1
To make this a tad easier just say 1/2 is 2/4.
0, 1/4, 2/4 __, 1
Now that you can see the pattern, the answer is clear as day.
