Whakaoti i te 4div8/3-3/5

$$4 \div \frac { 8 } { 3 } - \frac { 3 } { 5 }$$

Aromātai

$$\frac{9}{10}=0.9$$

Ngā Upane Otinga

Whakawehe 4 ki te \frac{8}{3} mā te whakarea 4 ki te tau huripoki o \frac{8}{3}.

$$4\times \frac{3}{8}-\frac{3}{5}$$

Tuhia te 4\times \frac{3}{8} hei hautanga kotahi.

$$\frac{4\times 3}{8}-\frac{3}{5}$$

Whakareatia te 4 ki te 3, ka 12.

$$\frac{12}{8}-\frac{3}{5}$$

Whakahekea te hautanga \frac{12}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{3}{2}-\frac{3}{5}$$

Ko te maha noa iti rawa atu o 2 me 5 ko 10. Me tahuri \frac{3}{2} me \frac{3}{5} ki te hautau me te tautūnga 10.

$$\frac{15}{10}-\frac{6}{10}$$

Tā te mea he rite te tauraro o \frac{15}{10} me \frac{6}{10}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15-6}{10}$$

Tangohia te 6 i te 15, ka 9.

$$\frac{9}{10}$$

Tauwehe

$$\frac{3 ^ {2}}{2 \cdot 5} = 0.9$$
