Step-by-Step Solution

To solve the exercise 110+3512 \frac{1}{10} + \frac{3}{5} - \frac{1}{2} , we must follow these steps:

Step 1: Find the Least Common Denominator (LCD).
The denominators we have are 10, 5, and 2. The LCD for these numbers is 10.

Step 2: Convert each fraction to have the common denominator of 10.
- 110 \frac{1}{10} is already with the denominator 10.
- Convert 35 \frac{3}{5} :35×22=610 \frac{3}{5} \times \frac{2}{2} = \frac{6}{10}
- Convert 12 \frac{1}{2} :
12×55=510 \frac{1}{2} \times \frac{5}{5} = \frac{5}{10}

Step 3: Perform the addition and subtraction.
Now operate: 110+610510=1+6510=210 \frac{1}{10} + \frac{6}{10} - \frac{5}{10} = \frac{1 + 6 - 5}{10} = \frac{2}{10}

Step 4: Simplify the result.
The fraction 210\frac{2}{10} simplifies to 15\frac{1}{5} because both the numerator and denominator are divisible by 2.

Therefore, the solution to the problem is 15\frac{1}{5}.

Answer

15 \frac{1}{5}
