write the missing fraction or mixed number for each number line
0,1/3,2/3,1,____,____,____,______,2 1/3
3
So, first determine how far the first few numbers are apart to figure out a pattern. Zero to 1/3 is 1/3 and 1/3 to 2/3 is also 1/3. 2/3 to 1 is also an addition of 1/3. So, it seems like you have established a pattern of adding 1/3 to every preceding term (number). Now, add 1/3 to 1 and then 1/3 to that term.
So, you will have: 1 + 1/3= 3/3 + 1/3= 4/3
4/3 + 1/3= 5/3
5/3 + 1/3= 6/3= 2
And it looks like you are done!
Hope this helps!
