#6 2/3#

Explanation:

Let's start by making these into improper fractions:

#4 1/6 = 25/6#

#-2 1/2 = -5/2#

After that we can properly subtract them, as such:

#25/6 - (-5/2)#
#25/6 + 5/2#
#25/6+15/6# (Make the denominators the same number)
#40/6 = 6 2/3#

Hope this helps!

#6 2/3#

Explanation:

When you subtract change the sign of the number to be subtracted and add.
Before doing it change the numbers to full fraction
So we have
#4 1/6 = 25/6#
#2 1/2 = 5/2#
Now add them
#25/6 + 5/2 = 25/6 + 15/6 = 40/6#
Now simplify the fraction
#40/6 = 20/3 = 6 2/3#

#6 2/3#

Explanation:

If you look at a graphical number line, you can see that the negative of a negative number is just the "positive" (it just switches the direction along the line).

#4 1/6 - -2 1/2 = 4 1/6 + 2 1/2#
From here we just need to express both fractions with equal denominators. 2 is a factor of 6, so we will use 6.
#4 1/6 + 2 1/2 = 4 1/6 + 2 3/6 = 6 4/6# or #6 2/3#
