Q. Subtract. \newline34−38=\frac{3}{4} - \frac{3}{8} = ____ \newlineUse the model to help you.
  1. Find common denominator: Find a common denominator for the fractions 34\frac{3}{4} and 38\frac{3}{8}. The least common denominator here is 88.\newlineCalculation: 34=68\frac{3}{4} = \frac{6}{8} (since 4×2=84\times2 = 8, multiply both numerator and denominator of 34\frac{3}{4} by 22).
  2. Calculate subtraction: Now subtract the two fractions.\newlineCalculation: 68−38=38\frac{6}{8} - \frac{3}{8} = \frac{3}{8}.
