Camau Ateb

Troswch y rhif degol 22 i’r ffracsiwn \frac{88}{4}.

$$1725+\frac{\frac{99}{4}-\frac{88}{4}}{17}\times 6$$

Gan fod gan \frac{99}{4} a \frac{88}{4} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$1725+\frac{\frac{99-88}{4}}{17}\times 6$$

Tynnu 88 o 99 i gael 11.

$$1725+\frac{\frac{11}{4}}{17}\times 6$$

Mynegwch \frac{\frac{11}{4}}{17} fel ffracsiwn unigol.

$$1725+\frac{11}{4\times 17}\times 6$$

Lluosi 4 a 17 i gael 68.

$$1725+\frac{11}{68}\times 6$$

Mynegwch \frac{11}{68}\times 6 fel ffracsiwn unigol.

$$1725+\frac{11\times 6}{68}$$

Lluosi 11 a 6 i gael 66.

$$1725+\frac{66}{68}$$

Lleihau'r ffracsiwn \frac{66}{68} i'r graddau lleiaf posib drwy dynnu a chanslo allan 2.

$$1725+\frac{33}{34}$$

Troswch y rhif degol 1725 i’r ffracsiwn \frac{58650}{34}.

$$\frac{58650}{34}+\frac{33}{34}$$

Gan fod gan \frac{58650}{34} a \frac{33}{34} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{58650+33}{34}$$

Adio 58650 a 33 i gael 58683.

$$\frac{58683}{34}$$

Ffactor

$$\frac{3 \cdot 31 \cdot 631}{2 \cdot 17} = 1725\frac{33}{34} = 1725.9705882352941$$
