Whakaoti i te 2/3a+3b-3/2a+2b

$$\frac { 2 } { 3 a + 3 b } - \frac { 3 } { 2 a + 2 b }$$

Aromātai

$$-\frac{5}{6\left(a+b\right)}$$

Ngā Hipanga Rongoā Poto

Tauwehea te 3a+3b. Tauwehea te 2a+2b.

$$\frac{2}{3\left(a+b\right)}-\frac{3}{2\left(a+b\right)}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 3\left(a+b\right) me 2\left(a+b\right) ko 6\left(a+b\right). Whakareatia \frac{2}{3\left(a+b\right)} ki te \frac{2}{2}. Whakareatia \frac{3}{2\left(a+b\right)} ki te \frac{3}{3}.

$$\frac{2\times 2}{6\left(a+b\right)}-\frac{3\times 3}{6\left(a+b\right)}$$

Tā te mea he rite te tauraro o \frac{2\times 2}{6\left(a+b\right)} me \frac{3\times 3}{6\left(a+b\right)}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{2\times 2-3\times 3}{6\left(a+b\right)}$$

Mahia ngā whakarea i roto o 2\times 2-3\times 3.

$$\frac{4-9}{6\left(a+b\right)}$$

Mahia ngā tātaitai i roto o 4-9.

$$\frac{-5}{6\left(a+b\right)}$$

Whakarohaina te 6\left(a+b\right).

$$\frac{-5}{6a+6b}$$

Tauwehe

$$-\frac{5}{6\left(a+b\right)}$$
