Whakaoti i te 3/4+3/8div2/3

$$\frac { 3 } { 4 } + \frac { 3 } { 8 } \div \frac { 2 } { 3 }$$

Aromātai

$$\frac{21}{16}=1.3125$$

Ngā Upane Otinga

Whakawehe \frac{3}{8} ki te \frac{2}{3} mā te whakarea \frac{3}{8} ki te tau huripoki o \frac{2}{3}.

$$\frac{3}{4}+\frac{3}{8}\times \frac{3}{2}$$

Me whakarea te \frac{3}{8} ki te \frac{3}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3}{4}+\frac{3\times 3}{8\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{3\times 3}{8\times 2}.

$$\frac{3}{4}+\frac{9}{16}$$

Ko te maha noa iti rawa atu o 4 me 16 ko 16. Me tahuri \frac{3}{4} me \frac{9}{16} ki te hautau me te tautūnga 16.

$$\frac{12}{16}+\frac{9}{16}$$

Tā te mea he rite te tauraro o \frac{12}{16} me \frac{9}{16}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{12+9}{16}$$

Tāpirihia te 12 ki te 9, ka 21.

$$\frac{21}{16}$$

Tauwehe

$$\frac{3 \cdot 7}{2 ^ {4}} = 1\frac{5}{16} = 1.3125$$
