Whakaoti i te x/5+2x/10=20/15

$$\frac{ x }{ 5 } + \frac{ 2x }{ 10 } = \frac{ 20 }{ 15 }$$

Whakaoti mō x

$$x = \frac{10}{3} = 3\frac{1}{3} \approx 3.333333333$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 30, arā, te tauraro pātahi he tino iti rawa te kitea o 5,10,15.

$$6x+3\times 2x=2\times 20$$

Whakareatia te 3 ki te 2, ka 6.

$$6x+6x=2\times 20$$

Pahekotia te 6x me 6x, ka 12x.

$$12x=2\times 20$$

Whakareatia te 2 ki te 20, ka 40.

$$12x=40$$

Whakawehea ngā taha e rua ki te 12.

$$x=\frac{40}{12}$$

Whakahekea te hautanga \frac{40}{12} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x=\frac{10}{3}$$
