Datrys (24+(3-8-4)div(4-9)

$$(24+(3-8-4) \div (4-9)$$

Enrhifo

$$\frac{129}{5}=25.8$$

Camau Ateb

Tynnu 8 o 3 i gael -5.

$$24+\frac{-5-4}{4-9}$$

Tynnu 4 o -5 i gael -9.

$$24+\frac{-9}{4-9}$$

Tynnu 9 o 4 i gael -5.

$$24+\frac{-9}{-5}$$

Gellir symlhau’r ffracsiwn \frac{-9}{-5} i \frac{9}{5} drwy dynnu’r arwydd negatif o’r rhifiadur a’r enwadur.

$$24+\frac{9}{5}$$

Troswch y rhif degol 24 i’r ffracsiwn \frac{120}{5}.

$$\frac{120}{5}+\frac{9}{5}$$

Gan fod gan \frac{120}{5} a \frac{9}{5} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{120+9}{5}$$

Adio 120 a 9 i gael 129.

$$\frac{129}{5}$$

Ffactor

$$\frac{3 \cdot 43}{5} = 25\frac{4}{5} = 25.8$$
