• how do you do a line plot
• I still don't get it, could someone please explain?
• How do you now if it is 3 4ths or 8 fourths on a numberline
• Three fourths as a fraction is written as 3/4, where eight fourths is written as 8/4. Because 8 and 4 share factors, this fraction can be reduced, so 8/4=2. On a number line you would be able to tell that these are different because 2 is a whole number, so it would be on a main line, and 3/4 is not, so it would be in between the lines for 0 and 1.
