Q. Complete the equation. Write the sum as a mixed number.\newline43+27=21+21= \frac{4}{3}+\frac{2}{7}=\frac{\square}{21}+\frac{\square}{21}=\square \frac{\square}{\square}
  1. Find Common Denominator: Find a common denominator for the fractions 43\frac{4}{3} and 27\frac{2}{7}.\newlineTo add fractions, they must have the same denominator. The least common denominator (LCD) of 33 and 77 is 2121.
  2. Convert Fractions to 2121: Convert each fraction to have the denominator 2121.\newline(43)=(4×73×7)=2821(\frac{4}{3}) = (\frac{4\times7}{3\times7}) = \frac{28}{21}\newline(27)=(2×37×3)=621(\frac{2}{7}) = (\frac{2\times3}{7\times3}) = \frac{6}{21}
  3. Add Fractions: Add the fractions with the common denominator.\newline2821+621=28+621=3421\frac{28}{21} + \frac{6}{21} = \frac{28 + 6}{21} = \frac{34}{21}
  4. Convert to Mixed Number: Convert the improper fraction to a mixed number. 3421=11321\frac{34}{21} = 1 \frac{13}{21} (since 3434 divided by 2121 is 11 with a remainder of 1313)
