$$4.8 \div \frac{ 8 }{ 3 } +5.2 \times \frac{ 3 }{ 8 }$$

Aromātai

$$3.75$$

Ngā Upane Otinga

Whakawehe 4.8 ki te \frac{8}{3} mā te whakarea 4.8 ki te tau huripoki o \frac{8}{3}.

$$4.8\times \frac{3}{8}+5.2\times \frac{3}{8}$$

Me tahuri ki tau ā-ira 4.8 ki te hautau \frac{48}{10}. Whakahekea te hautanga \frac{48}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{24}{5}\times \frac{3}{8}+5.2\times \frac{3}{8}$$

Me whakarea te \frac{24}{5} ki te \frac{3}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{24\times 3}{5\times 8}+5.2\times \frac{3}{8}$$

Mahia ngā whakarea i roto i te hautanga \frac{24\times 3}{5\times 8}.

$$\frac{72}{40}+5.2\times \frac{3}{8}$$

Whakahekea te hautanga \frac{72}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.

$$\frac{9}{5}+5.2\times \frac{3}{8}$$

Me tahuri ki tau ā-ira 5.2 ki te hautau \frac{52}{10}. Whakahekea te hautanga \frac{52}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{9}{5}+\frac{26}{5}\times \frac{3}{8}$$

Me whakarea te \frac{26}{5} ki te \frac{3}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{9}{5}+\frac{26\times 3}{5\times 8}$$

Mahia ngā whakarea i roto i te hautanga \frac{26\times 3}{5\times 8}.

$$\frac{9}{5}+\frac{78}{40}$$

Whakahekea te hautanga \frac{78}{40} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$\frac{9}{5}+\frac{39}{20}$$

Ko te maha noa iti rawa atu o 5 me 20 ko 20. Me tahuri \frac{9}{5} me \frac{39}{20} ki te hautau me te tautūnga 20.

$$\frac{36}{20}+\frac{39}{20}$$

Tā te mea he rite te tauraro o \frac{36}{20} me \frac{39}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{36+39}{20}$$

Tāpirihia te 36 ki te 39, ka 75.

$$\frac{75}{20}$$

Whakahekea te hautanga \frac{75}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$\frac{15}{4}$$

Tauwehe

$$\frac{3 \cdot 5}{2 ^ {2}} = 3\frac{3}{4} = 3.75$$
