Whakaoti i te x+35/8=71/4

$$x + 3 \frac { 5 } { 8 } = 7 \frac { 1 } { 4 }$$

Whakaoti mō x

$$x = \frac{29}{8} = 3\frac{5}{8} = 3.625$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua o te whārite ki te 8, arā, te tauraro pātahi he tino iti rawa te kitea o 8,4.

$$8x+3\times 8+5=2\left(7\times 4+1\right)$$

Whakareatia te 3 ki te 8, ka 24.

$$8x+24+5=2\left(7\times 4+1\right)$$

Tāpirihia te 24 ki te 5, ka 29.

$$8x+29=2\left(7\times 4+1\right)$$

Whakareatia te 7 ki te 4, ka 28.

$$8x+29=2\left(28+1\right)$$

Tāpirihia te 28 ki te 1, ka 29.

$$8x+29=2\times 29$$

Whakareatia te 2 ki te 29, ka 58.

$$8x+29=58$$

Tangohia te 29 mai i ngā taha e rua.

$$8x=58-29$$

Tangohia te 29 i te 58, ka 29.

$$8x=29$$

Whakawehea ngā taha e rua ki te 8.

$$x=\frac{29}{8}$$
