Tohaina
Kua tāruatia ki te papatopenga
4d-7=\frac{25}{4}
Pahekotia te 3d me d, ka 4d.
4d=\frac{25}{4}+7
Me tāpiri te 7 ki ngā taha e rua.
4d=\frac{25}{4}+\frac{28}{4}
Me tahuri te 7 ki te hautau \frac{28}{4}.
4d=\frac{25+28}{4}
Tā te mea he rite te tauraro o \frac{25}{4} me \frac{28}{4}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
4d=\frac{53}{4}
Tāpirihia te 25 ki te 28, ka 53.
d=\frac{\frac{53}{4}}{4}
Whakawehea ngā taha e rua ki te 4.
d=\frac{53}{4\times 4}
Tuhia te \frac{\frac{53}{4}}{4} hei hautanga kotahi.
d=\frac{53}{16}
Whakareatia te 4 ki te 4, ka 16.
