$$2 ( \frac { 1 } { 5 } m - \frac { 2 } { 5 } ) + \frac { 3 } { 5 }$$

Evalwa

$$\frac{2m-1}{5}$$

Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika 2 b'\frac{1}{5}m-\frac{2}{5}.

$$2\times \frac{1}{5}m+2\left(-\frac{2}{5}\right)+\frac{3}{5}$$

Immultiplika 2 u \frac{1}{5} biex tikseb \frac{2}{5}.

$$\frac{2}{5}m+2\left(-\frac{2}{5}\right)+\frac{3}{5}$$

Esprimi 2\left(-\frac{2}{5}\right) bħala frazzjoni waħda.

$$\frac{2}{5}m+\frac{2\left(-2\right)}{5}+\frac{3}{5}$$

Immultiplika 2 u -2 biex tikseb -4.

$$\frac{2}{5}m+\frac{-4}{5}+\frac{3}{5}$$

Frazzjoni \frac{-4}{5} tista' tinkiteb mill-ġdid bħala -\frac{4}{5} bl-estrazzjoni tas-sinjal negattiv.

$$\frac{2}{5}m-\frac{4}{5}+\frac{3}{5}$$

Billi -\frac{4}{5} u \frac{3}{5} għandhom l-istess denominatur, żidhom billi żżid in-numeraturi tagħhom.

$$\frac{2}{5}m+\frac{-4+3}{5}$$

Żid -4 u 3 biex tikseb -1.

$$\frac{2}{5}m-\frac{1}{5}$$
