Whakaoti i te 5/8-7/16*1/2

$$\frac { 5 } { 8 } - \frac { 7 } { 16 } \times \frac { 1 } { 2 }$$

Aromātai

$$\frac{13}{32}=0.40625$$

Ngā Upane Otinga

Me whakarea te \frac{7}{16} ki te \frac{1}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{5}{8}-\frac{7\times 1}{16\times 2}$$

Mahia ngā whakarea i roto i te hautanga \frac{7\times 1}{16\times 2}.

$$\frac{5}{8}-\frac{7}{32}$$

Ko te maha noa iti rawa atu o 8 me 32 ko 32. Me tahuri \frac{5}{8} me \frac{7}{32} ki te hautau me te tautūnga 32.

$$\frac{20}{32}-\frac{7}{32}$$

Tā te mea he rite te tauraro o \frac{20}{32} me \frac{7}{32}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{20-7}{32}$$

Tangohia te 7 i te 20, ka 13.

$$\frac{13}{32}$$

Tauwehe

$$\frac{13}{2 ^ {5}} = 0.40625$$
