m-5=\frac{10}{0.8}
Whakawehea ngā taha e rua ki te 0.8.
m-5=\frac{100}{8}
Whakarohaina te \frac{10}{0.8} mā te whakarea i te taurunga me te tauraro ki te 10.
m-5=\frac{25}{2}
Whakahekea te hautanga \frac{100}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
m=\frac{25}{2}+5
Me tāpiri te 5 ki ngā taha e rua.
m=\frac{25}{2}+\frac{10}{2}
Me tahuri te 5 ki te hautau \frac{10}{2}.
m=\frac{25+10}{2}
Tā te mea he rite te tauraro o \frac{25}{2} me \frac{10}{2}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
m=\frac{35}{2}
Tāpirihia te 25 ki te 10, ka 35.
