Whakaoti mō c
c = \frac{5}{4} = 1\frac{1}{4} = 1.25
Tohaina
Kua tāruatia ki te papatopenga
5c-4+3c=6
Me tāpiri te 3c ki ngā taha e rua.
8c-4=6
Pahekotia te 5c me 3c, ka 8c.
8c=6+4
Me tāpiri te 4 ki ngā taha e rua.
8c=10
Tāpirihia te 6 ki te 4, ka 10.
c=\frac{10}{8}
Whakawehea ngā taha e rua ki te 8.
c=\frac{5}{4}
Whakahekea te hautanga \frac{10}{8} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
