x_{5} = \frac{25}{7} = 3\frac{4}{7} \approx 3.571428571
Tohaina
Kua tāruatia ki te papatopenga
x_{5}=5\times \frac{5}{7}
Me whakarea ngā taha e rua ki te \frac{5}{7}, te tau utu o \frac{7}{5}.
x_{5}=\frac{5\times 5}{7}
Tuhia te 5\times \frac{5}{7} hei hautanga kotahi.
x_{5}=\frac{25}{7}
Whakareatia te 5 ki te 5, ka 25.
