Passi tas-Soluzzjonijiet

Ikkalkula 10 bil-power ta' -1 u tikseb \frac{1}{10}.

$$4.32\times \frac{1}{10}-2.5\times 10^{-1}\times 115$$

Immultiplika 4.32 u \frac{1}{10} biex tikseb \frac{54}{125}.

$$\frac{54}{125}-2.5\times 10^{-1}\times 115$$

Ikkalkula 10 bil-power ta' -1 u tikseb \frac{1}{10}.

$$\frac{54}{125}-2.5\times \frac{1}{10}\times 115$$

Immultiplika 2.5 u \frac{1}{10} biex tikseb \frac{1}{4}.

$$\frac{54}{125}-\frac{1}{4}\times 115$$

Immultiplika \frac{1}{4} u 115 biex tikseb \frac{115}{4}.

$$\frac{54}{125}-\frac{115}{4}$$
