Whakaoti i te 4x:1/3=(3-x):0.75

$$4 x : \frac { 1 } { 3 } = ( 3 - x ) : 0.75$$

Whakaoti mō x

$$x=0.3$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 4x ki te \frac{1}{3}, kia riro ko 12x.

$$12x=\frac{3-x}{0.75}$$

Whakawehea ia wā o 3-x ki te 0.75, kia riro ko \frac{3}{0.75}+\frac{-x}{0.75}.

$$12x=\frac{3}{0.75}+\frac{-x}{0.75}$$

Whakarohaina te \frac{3}{0.75} mā te whakarea i te taurunga me te tauraro ki te 100.

$$12x=\frac{300}{75}+\frac{-x}{0.75}$$

Whakawehea te 300 ki te 75, kia riro ko 4.

$$12x=4+\frac{-x}{0.75}$$

Whakawehea te -x ki te 0.75, kia riro ko -\frac{4}{3}x.

$$12x=4-\frac{4}{3}x$$

Me tāpiri te \frac{4}{3}x ki ngā taha e rua.

$$12x+\frac{4}{3}x=4$$

Pahekotia te 12x me \frac{4}{3}x, ka \frac{40}{3}x.

$$\frac{40}{3}x=4$$

Whakawehea ngā taha e rua ki te \frac{40}{3}.

$$x=\frac{4}{\frac{40}{3}}$$
