5 raruraru e ōrite ana ki:
\frac{ 1 }{ 7 } x- \frac{ 5 }{ 7 } = \frac{ 8 }{ 7 }
Tohaina
Kua tāruatia ki te papatopenga
\frac{1}{7}x=\frac{8}{7}+\frac{5}{7}
Me tāpiri te \frac{5}{7} ki ngā taha e rua.
\frac{1}{7}x=\frac{8+5}{7}
Tā te mea he rite te tauraro o \frac{8}{7} me \frac{5}{7}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
\frac{1}{7}x=\frac{13}{7}
Tāpirihia te 8 ki te 5, ka 13.
x=\frac{13}{7}\times 7
Me whakarea ngā taha e rua ki te 7, te tau utu o \frac{1}{7}.
x=13
Me whakakore te 7 me te 7.
