Question

`165z^(3)` divided by 210z

please help me ://

Answer 1

`\frac{11 {z}^(2) }{14}`

Explanation:

`\frac{165 {z}^(3) }{210z} = \frac{165 * {z}^(3) }{210 * z} = (165)/(210) * \frac{ {z}^(3) }{z}`

Now lets reduce the numerator and denominator with their common factors.

• Common factor of 165 and 210 => 15
• Common factor of
  `z^(3)` and z => z

So ,

`= > (165)/(210) * \frac{ {z}^(3) }{z} = (11)/(14) * {z}^(2) = \frac{11 {z}^(2) }{14}`
