5 raruraru e ōrite ana ki:
- 0.3 + \frac { 4 } { 5 } \times ( - 2 \frac { 1 } { 2 } )
Tohaina
Kua tāruatia ki te papatopenga
-0.3+\frac{4}{5}\left(-\frac{4+1}{2}\right)
Whakareatia te 2 ki te 2, ka 4.
-0.3+\frac{4}{5}\left(-\frac{5}{2}\right)
Tāpirihia te 4 ki te 1, ka 5.
-0.3+\frac{4\left(-5\right)}{5\times 2}
Me whakarea te \frac{4}{5} ki te -\frac{5}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.
-0.3+\frac{-20}{10}
Mahia ngā whakarea i roto i te hautanga \frac{4\left(-5\right)}{5\times 2}.
-0.3-2
Whakawehea te -20 ki te 10, kia riro ko -2.
-2.3
Tangohia te 2 i te -0.3, ka -2.3.
