\left(\frac{5q}{45q\alpha }+\frac{9\alpha }{45q\alpha }\right)\times \frac{\alpha ^{2}}{28}

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. L-inqas multiplu komuni ta' 9\alpha u 5q huwa 45q\alpha . Immultiplika \frac{1}{9\alpha } b'\frac{5q}{5q}. Immultiplika \frac{1}{5q} b'\frac{9\alpha }{9\alpha }.

\frac{5q+9\alpha }{45q\alpha }\times \frac{\alpha ^{2}}{28}

Billi \frac{5q}{45q\alpha } u \frac{9\alpha }{45q\alpha } għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

\frac{\left(5q+9\alpha \right)\alpha ^{2}}{45q\alpha \times 28}

Immultiplika \frac{5q+9\alpha }{45q\alpha } b'\frac{\alpha ^{2}}{28} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

\frac{\alpha \left(5q+9\alpha \right)}{28\times 45q}

Annulla \alpha fin-numeratur u d-denominatur.

\frac{\alpha \left(5q+9\alpha \right)}{1260q}

Immultiplika 28 u 45 biex tikseb 1260.

\frac{5\alpha q+9\alpha ^{2}}{1260q}

Uża l-propjetà distributtiva biex timmultiplika \alpha b'5q+9\alpha .

\left(\frac{5q}{45q\alpha }+\frac{9\alpha }{45q\alpha }\right)\times \frac{\alpha ^{2}}{28}

\frac{5q+9\alpha }{45q\alpha }\times \frac{\alpha ^{2}}{28}
