Ffactorial 5 yw 120.

$$\frac{120}{3!\left(5-3\right)!}\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Ffactorial 3 yw 6.

$$\frac{120}{6\left(5-3\right)!}\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Tynnu 3 o 5 i gael 2.

$$\frac{120}{6\times 2!}\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Ffactorial 2 yw 2.

$$\frac{120}{6\times 2}\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Lluosi 6 a 2 i gael 12.

$$\frac{120}{12}\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Rhannu 120 â 12 i gael 10.

$$10\times \left(\frac{1}{4}\right)^{3}\times \left(\frac{3}{4}\right)^{2}$$

Cyfrifo \frac{1}{4} i bŵer 3 a chael \frac{1}{64}.

$$10\times \frac{1}{64}\times \left(\frac{3}{4}\right)^{2}$$

Lluosi 10 a \frac{1}{64} i gael \frac{10}{64}.

$$\frac{10}{64}\times \left(\frac{3}{4}\right)^{2}$$

Lleihau'r ffracsiwn \frac{10}{64} i'r graddau lleiaf posib drwy dynnu a chanslo allan 2.

$$\frac{5}{32}\times \left(\frac{3}{4}\right)^{2}$$

Cyfrifo \frac{3}{4} i bŵer 2 a chael \frac{9}{16}.

$$\frac{5}{32}\times \frac{9}{16}$$

Lluoswch \frac{5}{32} â \frac{9}{16} drwy luosi'r rhifiadur â’r rhifiadur a'r enwadur â’r enwadur.

$$\frac{5\times 9}{32\times 16}$$

Gwnewch y gwaith lluosi yn y ffracsiwn \frac{5\times 9}{32\times 16}.

$$\frac{45}{512}$$

Ffactor

$$\frac{3 ^ {2} \cdot 5}{2 ^ {9}} = 0.087890625$$
