Find the distance between -5 2/5 and -1 3/10 on a number line

4 1/10

Step-by-step explanation:

-5 2/5 lies to the LEFT of -1 3/10.  To find the distance between these numbers on the number line, subtract -5 2/5 from -1 3/10:

Writing both numbers as improper fractions, we get:

-27/5 is to be subtracted from -13/10.

Here we see that the LCD is 10, so we change -27/5 to -54/10.  Now subtract

-54/10 from -13/10:

    -13/10

-(  -54/10  )

     41/10, or 4 1/10, represents the distance between -5 2/5 and -1 3/10.
