Tohaina
Kua tāruatia ki te papatopenga
16b-4=0
Pahekotia te -4b me 20b, ka 16b.
16b=4
Me tāpiri te 4 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
b=\frac{4}{16}
Whakawehea ngā taha e rua ki te 16.
b=\frac{1}{4}
Whakahekea te hautanga \frac{4}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.
