Answer:
Average of number is equal to sum of numbers by total no.
i.e.,
Now when numbers/amounts are fraction then there is one extra step which is to add the fractions.
Lets say we have to find average of 2 fractions i.e.,
Step 1 : First to add the fractions find the LCM of denominator as There are unlike fractions
3 = 1 × 3
4 = 1 × 4
LCM of 3 and 4 = 3 × 4 = 12
Step 2: To make them like fraction we find equivalent fraction of each fraction whose denominator equal to 12
Step 3: Adding both fractions
Step 4: put these value in average formula
Step 5: Now we divideby 2 using fraction division .i.e., multiply the reciprocal of divisor with dividend
here 2 is divisor
Reciprocal =
Following these steps Average of fractional amount of any no can be found.

Answer: -a - 2b -9c
Step-by-step explanation:
-2a - (-a) = -a
-4b - (-2b) = -2b
-6c - (3c) = -9c
-a - 2b - 9c

What is Combining Like Terms?
Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials.
How to Combine Like Terms (Simplified):
remove parentheses by multiplying factors.
use exponent rules to remove parentheses in terms with exponents.
combine like terms by adding coefficients.
combine the constants.
Example: Explanation:
3x and -8x^2 Unlike terms - the exponents are different
Answer:
Combining like terms is a mathematical process used to simplify an expression or to add or subtract polynomials.
Step-by-step explanation:
How do I combine like terms?
1. Step 2: Combine the coefficients.
2. 5h + 11g + 1h - 8g.
3. (5 + 1)h + (11 - 8)g.
4. 6h + 3g.
5. Step 1: Organize your like terms.
6. 5x + 8x + 10x2 - 7x2 - 4x.
7. Step 2: Combine the coefficients. (5 + 8 - 4)x + (10 - 7)x2 9x + 3x2
