Ю) 56 \(\frac{1}{19}\) - 44 \(\frac{56}{57}\) = \(\frac{56 \cdot 19 + 1}{19}\) - \(\frac{44 \cdot 57 + 56}{57}\) = \(\frac{1064 + 1}{19}\) - \(\frac{2508 + 56}{57}\) = \(\frac{1065}{19}\) - \(\frac{2564}{57}\) = \(\frac{1065 \cdot 3}{19 \cdot 3}\) - \(\frac{2564}{57}\) = \(\frac{3195}{57}\) - \(\frac{2564}{57}\) = \(\frac{3195 - 2564}{57}\) = \(\frac{631}{57}\) = 11 \(\frac{4}{57}\)
