=======================================================
Explanation:
We'll start off converting each mixed number into an improper fraction.
The formula to use is
So,
And,
So the task of computing is exactly the same as computing
Notice how we have an 8 up top and an 8 down below. Those 8's cancel out and we're left with . That fraction does not reduce any further.
The last step is to convert that improper fraction result to a mixed number.
Or you could note that 17/3 leads to 5 remainder 2. The 5 is the whole part and the 2 forms the numerator of the fractional part 2/3.
The value is in form where
- A = 5
- b = 2
- c = 3
Therefore, A+b+c = 5+2+3 = 10
