Whakaoti i te (4/5*20/16)div(1/2+1/3)

$$( \frac { 4 } { 5 } \cdot \frac { 20 } { 16 } ) \div ( \frac { 1 } { 2 } + \frac { 1 } { 3 } )$$

Aromātai

$$\frac{6}{5}=1.2$$

Ngā Upane Otinga

Whakahekea te hautanga \frac{20}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

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

Me whakakore atu te \frac{4}{5} me tōna tau utu \frac{5}{4}.

$$\frac{1}{\frac{1}{2}+\frac{1}{3}}$$

Ko te maha noa iti rawa atu o 2 me 3 ko 6. Me tahuri \frac{1}{2} me \frac{1}{3} ki te hautau me te tautūnga 6.

$$\frac{1}{\frac{3}{6}+\frac{2}{6}}$$

Tā te mea he rite te tauraro o \frac{3}{6} me \frac{2}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1}{\frac{3+2}{6}}$$

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{1}{\frac{5}{6}}$$

Whakawehe 1 ki te \frac{5}{6} mā te whakarea 1 ki te tau huripoki o \frac{5}{6}.

$$1\times \frac{6}{5}$$

Whakareatia te 1 ki te \frac{6}{5}, ka \frac{6}{5}.

$$\frac{6}{5}$$

Tauwehe

$$\frac{2 \cdot 3}{5} = 1\frac{1}{5} = 1.2$$
