Whakaoti i te 3/8-1/2(3/4)^2

$$\frac { 3 } { 8 } - \frac { 1 } { 2 } ( \frac { 3 } { 4 } ) ^ { 2 }$$

Aromātai

$$\frac{3}{32}=0.09375$$

Ngā Upane Otinga

Tātaihia te \frac{3}{4} mā te pū o 2, kia riro ko \frac{9}{16}.

$$\frac{3}{8}-\frac{1}{2}\times \frac{9}{16}$$

Me whakarea te \frac{1}{2} ki te \frac{9}{16} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{3}{8}-\frac{1\times 9}{2\times 16}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 9}{2\times 16}.

$$\frac{3}{8}-\frac{9}{32}$$

Ko te maha noa iti rawa atu o 8 me 32 ko 32. Me tahuri \frac{3}{8} me \frac{9}{32} ki te hautau me te tautūnga 32.

$$\frac{12}{32}-\frac{9}{32}$$

Tā te mea he rite te tauraro o \frac{12}{32} me \frac{9}{32}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{12-9}{32}$$

Tangohia te 9 i te 12, ka 3.

$$\frac{3}{32}$$

Tauwehe

$$\frac{3}{2 ^ {5}} = 0.09375$$
