Whakawehe \frac{2\times 4+1}{4} ki te \frac{7}{4} mā te whakarea \frac{2\times 4+1}{4} ki te tau huripoki o \frac{7}{4}.

$$\frac{\left(2\times 4+1\right)\times 4}{4\times 7}=\frac{\frac{3}{2}}{5}$$

Me whakakore tahi te 4 i te taurunga me te tauraro.

$$\frac{1+2\times 4}{7}=\frac{\frac{3}{2}}{5}$$

Whakareatia te 2 ki te 4, ka 8.

$$\frac{1+8}{7}=\frac{\frac{3}{2}}{5}$$

Tāpirihia te 1 ki te 8, ka 9.

$$\frac{9}{7}=\frac{\frac{3}{2}}{5}$$

Tuhia te \frac{\frac{3}{2}}{5} hei hautanga kotahi.

$$\frac{9}{7}=\frac{3}{2\times 5}$$

Whakareatia te 2 ki te 5, ka 10.

$$\frac{9}{7}=\frac{3}{10}$$

Ko te maha noa iti rawa atu o 7 me 10 ko 70. Me tahuri \frac{9}{7} me \frac{3}{10} ki te hautau me te tautūnga 70.

$$\frac{90}{70}=\frac{21}{70}$$

Whakatauritea te \frac{90}{70} me te \frac{21}{70}.
