Kua tāruatia ki te papatopenga
6\left(-a-8b-\frac{7c}{4}\right)
Tuhia te 7\times \frac{c}{4} hei hautanga kotahi.
6\left(\frac{4\left(-a-8b\right)}{4}-\frac{7c}{4}\right)
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia -a-8b ki te \frac{4}{4}.
6\times \frac{4\left(-a-8b\right)-7c}{4}
Tā te mea he rite te tauraro o \frac{4\left(-a-8b\right)}{4} me \frac{7c}{4}, me tango rāua mā te tango i ō raua taurunga.
6\times \frac{-4a-32b-7c}{4}
Mahia ngā whakarea i roto o 4\left(-a-8b\right)-7c.
\frac{6\left(-4a-32b-7c\right)}{4}
Tuhia te 6\times \frac{-4a-32b-7c}{4} hei hautanga kotahi.
\frac{-24a-192b-42c}{4}
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te -4a-32b-7c.
6\left(-a-8b-\frac{7c}{4}\right)
Tuhia te 7\times \frac{c}{4} hei hautanga kotahi.
6\left(\frac{4\left(-a-8b\right)}{4}-\frac{7c}{4}\right)
Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia -a-8b ki te \frac{4}{4}.
6\times \frac{4\left(-a-8b\right)-7c}{4}
Tā te mea he rite te tauraro o \frac{4\left(-a-8b\right)}{4} me \frac{7c}{4}, me tango rāua mā te tango i ō raua taurunga.
6\times \frac{-4a-32b-7c}{4}
Mahia ngā whakarea i roto o 4\left(-a-8b\right)-7c.
\frac{6\left(-4a-32b-7c\right)}{4}
Tuhia te 6\times \frac{-4a-32b-7c}{4} hei hautanga kotahi.
\frac{-24a-192b-42c}{4}
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te -4a-32b-7c.
