Math Problem Statement

1/2 + 2/3

Solution

To add the fractions 12+23\frac{1}{2} + \frac{2}{3}, we need to find a common denominator.

Step 1: Find the Least Common Denominator (LCD)

The denominators are 2 and 3. The least common denominator is the smallest number that both 2 and 3 can divide into, which is 6.

Step 2: Convert Each Fraction to Have the LCD as the Denominator

  • For 12\frac{1}{2}, multiply the numerator and denominator by 3: 12=1×32×3=36\frac{1}{2} = \frac{1 \times 3}{2 \times 3} = \frac{3}{6}
  • For 23\frac{2}{3}, multiply the numerator and denominator by 2: 23=2×23×2=46\frac{2}{3} = \frac{2 \times 2}{3 \times 2} = \frac{4}{6}

Step 3: Add the Fractions

Now that both fractions have the same denominator, we can add them directly: 36+46=3+46=76\frac{3}{6} + \frac{4}{6} = \frac{3 + 4}{6} = \frac{7}{6}

Conclusion

The sum of 12+23\frac{1}{2} + \frac{2}{3} is:

76\frac{7}{6}
