Whakaoti mō b
b = \frac{5}{2} = 2\frac{1}{2} = 2.5
Tohaina
Kua tāruatia ki te papatopenga
\frac{4b}{1-0}=10
Whakareatia te 0 ki te 2, ka 0.
\frac{4b}{1}=10
Tangohia te 0 i te 1, ka 1.
4b=10
Ka whakawehea he tau ki te tahi, hua ai ko ia anō.
b=\frac{10}{4}
Whakawehea ngā taha e rua ki te 4.
b=\frac{5}{2}
Whakahekea te hautanga \frac{10}{4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
