Whakawehe \frac{\left(7-2\right)^{2}\times 2+4}{\sqrt{64}+3\times 4} ki te \frac{27}{10} mā te whakarea \frac{\left(7-2\right)^{2}\times 2+4}{\sqrt{64}+3\times 4} ki te tau huripoki o \frac{27}{10}.

$$\frac{\left(\left(7-2\right)^{2}\times 2+4\right)\times 10}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Tangohia te 2 i te 7, ka 5.

$$\frac{\left(5^{2}\times 2+4\right)\times 10}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Tātaihia te 5 mā te pū o 2, kia riro ko 25.

$$\frac{\left(25\times 2+4\right)\times 10}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Whakareatia te 25 ki te 2, ka 50.

$$\frac{\left(50+4\right)\times 10}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Tāpirihia te 50 ki te 4, ka 54.

$$\frac{54\times 10}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Whakareatia te 54 ki te 10, ka 540.

$$\frac{540}{\left(\sqrt{64}+3\times 4\right)\times 27}$$

Tātaitia te pūtakerua o 64 kia tae ki 8.

$$\frac{540}{\left(8+3\times 4\right)\times 27}$$

Whakareatia te 3 ki te 4, ka 12.

$$\frac{540}{\left(8+12\right)\times 27}$$

Tāpirihia te 8 ki te 12, ka 20.

$$\frac{540}{20\times 27}$$

Whakareatia te 20 ki te 27, ka 540.

$$\frac{540}{540}$$

Whakawehea te 540 ki te 540, kia riro ko 1.
