Step-by-Step Solution

To solve the problem, we need to evaluate the expression

56121226 \frac{5}{6} \cdot \frac{1}{2} - \frac{1}{2} \cdot \frac{2}{6} .

Let's go through this step-by-step:

  • Step 1:
    Calculate the first multiplication:
    5612=5162=512 \frac{5}{6} \cdot \frac{1}{2} = \frac{5 \cdot 1}{6 \cdot 2} = \frac{5}{12}
  • Step 2:
    Calculate the second multiplication:
    1226=1226=212 \frac{1}{2} \cdot \frac{2}{6} = \frac{1 \cdot 2}{2 \cdot 6} = \frac{2}{12} Simplify 212\frac{2}{12} by dividing the numerator and the denominator by their greatest common divisor, 2:
    212=16 \frac{2}{12} = \frac{1}{6}
  • Step 3:
    Subtract the second result from the first:
    Since we have 51216\frac{5}{12} - \frac{1}{6}, find a common denominator for the fractions, which is 12. Convert 16\frac{1}{6} to a denominator of 12:
    16=212 \frac{1}{6} = \frac{2}{12} Now, perform the subtraction:
    512212=312 \frac{5}{12} - \frac{2}{12} = \frac{3}{12} Simplify 312\frac{3}{12} by dividing the numerator and denominator by their greatest common divisor, 3:
    312=14 \frac{3}{12} = \frac{1}{4}

Therefore, the solution to the problem is 14 \frac{1}{4} .

Answer

14 \frac{1}{4}
