$$728 ( \frac { 3 } { 100 } ) + \frac { 10 } { 100 }$$

Aromātai

$$\frac{1097}{50}=21.94$$

Ngā Upane Otinga

Tuhia te 728\times \frac{3}{100} hei hautanga kotahi.

$$\frac{728\times 3}{100}+\frac{10}{100}$$

Whakareatia te 728 ki te 3, ka 2184.

$$\frac{2184}{100}+\frac{10}{100}$$

Whakahekea te hautanga \frac{2184}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$\frac{546}{25}+\frac{10}{100}$$

Whakahekea te hautanga \frac{10}{100} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 10.

$$\frac{546}{25}+\frac{1}{10}$$

Ko te maha noa iti rawa atu o 25 me 10 ko 50. Me tahuri \frac{546}{25} me \frac{1}{10} ki te hautau me te tautūnga 50.

$$\frac{1092}{50}+\frac{5}{50}$$

Tā te mea he rite te tauraro o \frac{1092}{50} me \frac{5}{50}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$\frac{1092+5}{50}$$

Tāpirihia te 1092 ki te 5, ka 1097.

$$\frac{1097}{50}$$

Tauwehe

$$\frac{1097}{2 \cdot 5 ^ {2}} = 21\frac{47}{50} = 21.94$$
