Whakaoti i te {l}{1/4+2/5}{1/4*1/5}

$$\left. \begin{array} { l } { \frac { 1 } { 4 } + \frac { 2 } { 5 } } \\ { \frac { 1 } { 4 } \times \frac { 1 } { 5 } } \end{array} \right.$$

Ngā Upane Otinga

Ko te maha noa iti rawa atu o 4 me 5 ko 20. Me tahuri \frac{1}{4} me \frac{2}{5} ki te hautau me te tautūnga 20.

$$sort(\frac{5}{20}+\frac{8}{20},\frac{1}{4}\times \frac{1}{5})$$

Tā te mea he rite te tauraro o \frac{5}{20} me \frac{8}{20}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$sort(\frac{5+8}{20},\frac{1}{4}\times \frac{1}{5})$$

Tāpirihia te 5 ki te 8, ka 13.

$$sort(\frac{13}{20},\frac{1}{4}\times \frac{1}{5})$$

Me whakarea te \frac{1}{4} ki te \frac{1}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$sort(\frac{13}{20},\frac{1\times 1}{4\times 5})$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 1}{4\times 5}.

$$sort(\frac{13}{20},\frac{1}{20})$$

Hei kōmaka i te rārangi, me tīmata mai i tētahi huānga \frac{13}{20} kotahi.

$$\frac{13}{20}$$

Me kōkuhu te \frac{1}{20} ki te tauwāhi tika i te rārangi hōu.

$$\frac{1}{20},\frac{13}{20}$$
