Datrys 21/5+8div5/6

$$2 \frac { 1 } { 5 } + 8 \div \frac { 5 } { 6 }$$

Enrhifo

$$\frac{59}{5}=11.8$$

Camau Ateb

Lluosi 2 a 5 i gael 10.

$$\frac{10+1}{5}+\frac{8}{\frac{5}{6}}$$

Adio 10 a 1 i gael 11.

$$\frac{11}{5}+\frac{8}{\frac{5}{6}}$$

Rhannwch 8 â \frac{5}{6} drwy luosi 8 â chilydd \frac{5}{6}.

$$\frac{11}{5}+8\times \frac{6}{5}$$

Mynegwch 8\times \frac{6}{5} fel ffracsiwn unigol.

$$\frac{11}{5}+\frac{8\times 6}{5}$$

Lluosi 8 a 6 i gael 48.

$$\frac{11}{5}+\frac{48}{5}$$

Gan fod gan \frac{11}{5} a \frac{48}{5} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{11+48}{5}$$

Adio 11 a 48 i gael 59.

$$\frac{59}{5}$$

Ffactor

$$\frac{59}{5} = 11\frac{4}{5} = 11.8$$
