Step-by-Step Solution

To solve the given problem 1227 \frac{1}{2} - \frac{2}{7} , we need to follow these steps:

  • Step 1: Find a common denominator for the fractions. The denominators are 2 and 7. The common denominator can be found by multiplying these two numbers: 2×7=14 2 \times 7 = 14 .
  • Step 2: Convert the fractions to equivalent fractions with the common denominator. For 12 \frac{1}{2} , multiply the numerator and the denominator by 7: 12=1×72×7=714 \frac{1}{2} = \frac{1 \times 7}{2 \times 7} = \frac{7}{14} . For 27 \frac{2}{7} , multiply the numerator and the denominator by 2: 27=2×27×2=414 \frac{2}{7} = \frac{2 \times 2}{7 \times 2} = \frac{4}{14} .
  • Step 3: Subtract the fractions. With a common denominator, subtract the numerators: 714414=7414=314 \frac{7}{14} - \frac{4}{14} = \frac{7 - 4}{14} = \frac{3}{14} .
  • Step 4: Simplify the resulting fraction if needed. The fraction 314\frac{3}{14} is already in its simplest form.

Thus, the solution to the problem is 314 \frac{3}{14} .

Answer

314 \frac{3}{14}
