Answer :
The number line we can see that 1.5 is less than 1.75.
Mark two points 1.75 and 1.5 on number line and make a number line from -1 to 2 where each point is 0.25 units away
Then compare 1.75 and 1.5 on number line
Given :
Nico wants to use a horizontal number line to compare 1 3/4 and 1.5
Lets write the fraction in decimal form to compare and mark it on number line [tex]1\frac{3}{4}[/tex] = 1.75
Now mark two points 1.75 and 1.5 on number line
Make a number line from -1 to 2 where each point is 0.25 units away
Mark a number line that are 0.25 units away using below numbers
-1, -0.75, -0.5, -0.25, 0, 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75, 2
On the number line ,
1.5 comes first
1.75 is next to 1.5
From this number line we can see that 1.5 is less than 1.75.
1.5 < [tex]1\frac{3}{4}[/tex]
Hence the answer is the number line we can see that 1.5 is less than 1.75.
