Whakaoti i te 2/5+4/3*3/5-(1/4)^2=

$$\frac { 2 } { 5 } + \frac { 4 } { 3 } \cdot \frac { 3 } { 5 } - ( \frac { 1 } { 4 } ) ^ { 2 } =$$

Aromātai

$$\frac{91}{80}=1.1375$$

Ngā Upane Otinga

Me whakarea te \frac{4}{3} ki te \frac{3}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{2}{5}+\frac{4\times 3}{3\times 5}-\left(\frac{1}{4}\right)^{2}$$

Me whakakore tahi te 3 i te taurunga me te tauraro.

$$\frac{2}{5}+\frac{4}{5}-\left(\frac{1}{4}\right)^{2}$$

Tā te mea he rite te tauraro o \frac{2}{5} me \frac{4}{5}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{2+4}{5}-\left(\frac{1}{4}\right)^{2}$$

Tāpirihia te 2 ki te 4, ka 6.

$$\frac{6}{5}-\left(\frac{1}{4}\right)^{2}$$

Tātaihia te \frac{1}{4} mā te pū o 2, kia riro ko \frac{1}{16}.

$$\frac{6}{5}-\frac{1}{16}$$

Ko te maha noa iti rawa atu o 5 me 16 ko 80. Me tahuri \frac{6}{5} me \frac{1}{16} ki te hautau me te tautūnga 80.

$$\frac{96}{80}-\frac{5}{80}$$

Tā te mea he rite te tauraro o \frac{96}{80} me \frac{5}{80}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{96-5}{80}$$

Tangohia te 5 i te 96, ka 91.

$$\frac{91}{80}$$

Tauwehe

$$\frac{7 \cdot 13}{2 ^ {4} \cdot 5} = 1\frac{11}{80} = 1.1375$$
