Whakaoti i te 20+29/frac{20{30}+29/40}=

$$\frac { 20 + 29 } { \frac { 20 } { 30 } + \frac { 29 } { 40 } } =$$

Aromātai

$$\frac{5880}{167}\approx 35.209580838$$

Ngā Upane Otinga

Tāpirihia te 20 ki te 29, ka 49.

$$\frac{49}{\frac{20}{30}+\frac{29}{40}}$$

Whakahekea te hautanga \frac{20}{30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\frac{49}{\frac{2}{3}+\frac{29}{40}}$$

Ko te maha noa iti rawa atu o 3 me 40 ko 120. Me tahuri \frac{2}{3} me \frac{29}{40} ki te hautau me te tautūnga 120.

$$\frac{49}{\frac{80}{120}+\frac{87}{120}}$$

Tā te mea he rite te tauraro o \frac{80}{120} me \frac{87}{120}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{49}{\frac{80+87}{120}}$$

Tāpirihia te 80 ki te 87, ka 167.

$$\frac{49}{\frac{167}{120}}$$

Whakawehe 49 ki te \frac{167}{120} mā te whakarea 49 ki te tau huripoki o \frac{167}{120}.

$$49\times \frac{120}{167}$$

Tuhia te 49\times \frac{120}{167} hei hautanga kotahi.

$$\frac{49\times 120}{167}$$

Whakareatia te 49 ki te 120, ka 5880.

$$\frac{5880}{167}$$

Tauwehe

$$\frac{2 ^ {3} \cdot 3 \cdot 5 \cdot 7 ^ {2}}{167} = 35\frac{35}{167} = 35.209580838323355$$
