Whakaoti i te 375+91/5+(-33/8)+(-4.2)

$$375 + 9 \frac { 1 } { 5 } + ( - 3 \frac { 3 } { 8 } ) + ( - 4.2 )$$

Aromātai

$$376.625$$

Ngā Upane Otinga

Whakareatia te 9 ki te 5, ka 45.

$$375+\frac{45+1}{5}-\frac{3\times 8+3}{8}-4.2$$

Tāpirihia te 45 ki te 1, ka 46.

$$375+\frac{46}{5}-\frac{3\times 8+3}{8}-4.2$$

Me tahuri te 375 ki te hautau \frac{1875}{5}.

$$\frac{1875}{5}+\frac{46}{5}-\frac{3\times 8+3}{8}-4.2$$

Tā te mea he rite te tauraro o \frac{1875}{5} me \frac{46}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1875+46}{5}-\frac{3\times 8+3}{8}-4.2$$

Tāpirihia te 1875 ki te 46, ka 1921.

$$\frac{1921}{5}-\frac{3\times 8+3}{8}-4.2$$

Whakareatia te 3 ki te 8, ka 24.

$$\frac{1921}{5}-\frac{24+3}{8}-4.2$$

Tāpirihia te 24 ki te 3, ka 27.

$$\frac{1921}{5}-\frac{27}{8}-4.2$$

Ko te maha noa iti rawa atu o 5 me 8 ko 40. Me tahuri \frac{1921}{5} me \frac{27}{8} ki te hautau me te tautūnga 40.

$$\frac{15368}{40}-\frac{135}{40}-4.2$$

Tā te mea he rite te tauraro o \frac{15368}{40} me \frac{135}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15368-135}{40}-4.2$$

Tangohia te 135 i te 15368, ka 15233.

$$\frac{15233}{40}-4.2$$

Me tahuri ki tau ā-ira 4.2 ki te hautau \frac{42}{10}. Whakahekea te hautanga \frac{42}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{15233}{40}-\frac{21}{5}$$

Ko te maha noa iti rawa atu o 40 me 5 ko 40. Me tahuri \frac{15233}{40} me \frac{21}{5} ki te hautau me te tautūnga 40.

$$\frac{15233}{40}-\frac{168}{40}$$

Tā te mea he rite te tauraro o \frac{15233}{40} me \frac{168}{40}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{15233-168}{40}$$

Tangohia te 168 i te 15233, ka 15065.

$$\frac{15065}{40}$$

Whakahekea te hautanga \frac{15065}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{3013}{8}$$

Tauwehe

$$\frac{23 \cdot 131}{2 ^ {3}} = 376\frac{5}{8} = 376.625$$
