(1) 393 2/3 (2) r-2t=X1/2Y-7/12. To calculate this, multiply the numerators and denominators of each fraction together and reduce: (X4/3 Y1/3) x (X1/2 Y-1/4) = (X2 Y-7/12). Then, set the numerator of each fraction equal to each other to find the value of r and t: X2 = Xr, Y-7/12 = Yt. Solving for r and t gives r=2 and t=-7/12. Thus, r-2t = X1/2Y-7/12.
