Whakaoti i te (1/10-1/12)*(51/4+075)

$$( \frac { 1 } { 10 } - \frac { 1 } { 12 } ) \times ( 5 \frac { 1 } { 4 } + 075 )$$

Aromātai

$$\frac{7}{80}=0.0875$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 10 me 12 ko 60. Me tahuri \frac{1}{10} me \frac{1}{12} ki te hautau me te tautūnga 60.

$$\left(\frac{6}{60}-\frac{5}{60}\right)\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Tā te mea he rite te tauraro o \frac{6}{60} me \frac{5}{60}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{6-5}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Tangohia te 5 i te 6, ka 1.

$$\frac{1}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

Whakareatia te 5 ki te 4, ka 20.

$$\frac{1}{60}\left(\frac{20+1}{4}+0\times 75\right)$$

Tāpirihia te 20 ki te 1, ka 21.

$$\frac{1}{60}\left(\frac{21}{4}+0\times 75\right)$$

Whakareatia te 0 ki te 75, ka 0.

$$\frac{1}{60}\left(\frac{21}{4}+0\right)$$

Tāpirihia te \frac{21}{4} ki te 0, ka \frac{21}{4}.

$$\frac{1}{60}\times \frac{21}{4}$$

Me whakarea te \frac{1}{60} ki te \frac{21}{4} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$\frac{1\times 21}{60\times 4}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 21}{60\times 4}.

$$\frac{21}{240}$$

Whakahekea te hautanga \frac{21}{240} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$\frac{7}{80}$$

Tauwehe

$$\frac{7}{2 ^ {4} \cdot 5} = 0.0875$$
