Whakaoti i te 2/3*x/5=8/15

$$\frac { 2 } { 3 } \cdot \frac { x } { 5 } = \frac { 8 } { 15 }$$

Whakaoti mō x

$$x=4$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.

$$\frac{x}{5}=\frac{8}{15}\times \frac{3}{2}$$

Me whakarea te \frac{8}{15} ki te \frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{x}{5}=\frac{8\times 3}{15\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{8\times 3}{15\times 2}.

$$\frac{x}{5}=\frac{24}{30}$$

Whakahekea te hautanga \frac{24}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 6.

$$\frac{x}{5}=\frac{4}{5}$$

Me whakarea ngā taha e rua ki te 5.

$$x=\frac{4}{5}\times 5$$

Me whakakore te 5 me te 5.

$$x=4$$
