To find the difference between two rational numbers, we can use the additive inverse. The additive inverse of a number "a" is the number that when added to "a" results in zero, denoted as "-a".
In this case, we want to find 8.76 - 26.54. Since the subtraction of two rational numbers is equivalent to adding the additive inverse of the second number, we can rewrite the problem as 8.76 + (-26.54).
To add these two numbers, align the decimal points and perform subtraction as you would with whole numbers:
8.76
+ (-26.54)
_________
Start by subtracting the hundredths place: 6 - 4 equals 2. Add the decimal point:
8.76
+ (-26.54)
_________
. 2
Next, subtract the tenths place: 7 - 5 equals 2:
8.76
+ (-26.54)
_________
2 . 2
Finally, subtract the ones place: 8 - 2 equals 6:
8.76
+ (-26.54)
_________
6 . 2
Now, bring down the negative sign from the second number (the additive inverse):
8.76
+ (-26.54)
_________
-6 . 2
Therefore, 8.76 - 26.54 is equal to -6.02.

To solve -12 2/3 - (-8 5/6), we can simplify the expression by converting mixed numbers into improper fractions and applying the rules of subtraction.
-12 2/3 can be written as -(38/3), and -(-8 5/6) can be written as -(-53/6).
Now, we need to subtract -(38/3) from -(-53/6). Remember that subtracting a negative number is equivalent to adding a positive number. Therefore, we have -(-53/6) + (38/3).
Next, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 3 and 6 is 6.
Converting the fractions to have a common denominator of 6, we get:
-(-53/6) + (38/3) = -(-53/6 * 2/2) + (38/3 * 2/2)
= -(-(106/12)) + (76/6)
= (106/12) + (76/6)
Now, we can add the fractions:
(106/12) + (76/6) = (106 + 152) / 12
= 258/12
Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 6.
258/12 can be simplified to 43/2.
Therefore, -12 2/3 - (-8 5/6) is equal to 43/2.
-12 2/3 can be written as -(38/3), and -(-8 5/6) can be written as -(-53/6).
Now, we need to subtract -(38/3) from -(-53/6). Remember that subtracting a negative number is equivalent to adding a positive number. Therefore, we have -(-53/6) + (38/3).
Next, we need to find a common denominator to add these fractions. The least common multiple (LCM) of 3 and 6 is 6.
Converting the fractions to have a common denominator of 6, we get:
-(-53/6) + (38/3) = -(-53/6 * 2/2) + (38/3 * 2/2)
= -(-(106/12)) + (76/6)
= (106/12) + (76/6)
Now, we can add the fractions:
(106/12) + (76/6) = (106 + 152) / 12
= 258/12
Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 6.
258/12 can be simplified to 43/2.
Therefore, -12 2/3 - (-8 5/6) is equal to 43/2.

To represent the absolute value of subtracting these rational numbers on a vertical line diagram, we start with a point representing the first number and then move downwards by the value of the second number.
The given numbers are -22 and 1 1/2.
We first represent -22 on the diagram by placing a point on the vertical line.
Next, we need to represent -1 1/2. To do this, we move downwards on the vertical line by 1 1/2 units.
Since 1 1/2 is equivalent to 3/2, we move downwards 3/2 units from the point representing -22.
Therefore, the absolute value of subtracting -22 and 1 1/2 on a vertical line diagram will be at the point reached after moving down by 3/2 units from the starting point representing -22.

To represent the absolute value of subtracting -22 and 1 1/2 on a vertical line diagram, we start by representing -22 on the diagram with a point or tick mark on the vertical line.
Next, we need to subtract 1 1/2 from -22. To do this, we move upwards on the vertical line by a distance of 1 1/2 units.
Since 1 1/2 is equivalent to 3/2, we move 3/2 units upwards from the point representing -22 on the diagram.
After moving upwards by 3/2 units, we reach a new point on the vertical line, which represents the result of subtracting -22 and 1 1/2.
To find the absolute value, we ignore the direction (up or down) and only consider the magnitude of the distance. So, in this case, the absolute value would be 3/2 or 1 1/2.
Therefore, the absolute value of subtracting -22 and 1 1/2 on a vertical line diagram is represented by a distance of 1 1/2 units upwards from the starting point of -22.
