$$5.8+\frac{0.2}{10}$$

Ehangu \frac{0.2}{10} drwy luosi'r rhifiadur a'r enwadur gyda 10.

$$5.8+\frac{2}{100}$$

Lleihau'r ffracsiwn \frac{2}{100} i'r graddau lleiaf posib drwy dynnu a chanslo allan 2.

$$5.8+\frac{1}{50}$$

Troswch y rhif degol 5.8 i’r ffracsiwn \frac{58}{10}. Lleihau'r ffracsiwn \frac{58}{10} i'r graddau lleiaf posib drwy dynnu a chanslo allan 2.

$$\frac{29}{5}+\frac{1}{50}$$

Lluosrif lleiaf cyffredin 5 a 50 yw 50. Troswch \frac{29}{5} a \frac{1}{50} yn ffracsiynau gyda’r enwadur 50.

$$\frac{290}{50}+\frac{1}{50}$$

Gan fod gan \frac{290}{50} a \frac{1}{50} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{290+1}{50}$$

Adio 290 a 1 i gael 291.

$$\frac{291}{50}$$

Ffactor

$$\frac{3 \cdot 97}{2 \cdot 5 ^ {2}} = 5\frac{41}{50} = 5.82$$
