−49−2−3=−49−−23\dfrac{-4}{9} - \dfrac{2}{-3}\\[1em] =\dfrac{-4}{9} - \dfrac{-2}{3}9−4−−32=9−4−3−2
LCM of 9 and 3 is 3 x 3 = 9
−4×19×1−−2×33×3=−49−−69=−4−(−6)9=−4+69=29\dfrac{-4 \times 1}{9 \times 1} - \dfrac{-2 \times 3}{3 \times 3}\\[1em] = \dfrac{-4}{9} - \dfrac{-6}{9}\\[1em] = \dfrac{-4 - (-6)}{9}\\[1em] = \dfrac{-4 + 6}{9}\\[1em] = \dfrac{2}{9}9×1−4×1−3×3−2×3=9−4−9−6=9−4−(−6)=9−4+6=92
