To solve this problem first turn the mixed number in the middle to an improper fraction.
Turn mixed numbers into improper fractions by multiplying the whole number by the denominator (bottom number) and add the numerator (top number) to find a new numerator.
So 1x2 = 2 + 1 = 3. The improper fraction would be 3/2.
Next, find a common denominator (bottom number) for all 3 fractions. Do this by finding a common multiple of all 3 numbers (6, 2, and 3). This would be 6.
Whatever you do to the bottom number you must do for the top as well.
The first fraction stays the same - 5/6
The middle fraction would have to be multiplied by 3 (top and bottom) to make 9/6
The last fraction would have to be multiplied by 2 (top and bottom) to make 4/6
New equation: 5/6 + 9/6 + 4/6
Add all of the numerators (top numbers) : 5 + 9 + 4 = 18
The denominator (bottom number) stays the same.
The answer is 18/6. To turn this back into a whole number or mixed number divide the numerator by the denominator. This would give you 3.
Final Answer: 18/6 = 3
