Question

On dividing 57p²qr by 114pq, we get ______.

Options

• ${\displaystyle \frac{1}{4}pr}$

• ${\displaystyle \frac{3}{4}pr}$

• ${\displaystyle \frac{1}{2}pr}$

• ${\displaystyle 2pr}$

Answer 1

On dividing 57p²qr by 114pq, we get ${\displaystyle \underline{\frac{1}{2}pr}}$.

Explanation:

Required value = ${\displaystyle \frac{57p^{2}qr}{114pq}}$

= ${\displaystyle \frac{57\times p\times p\times q\times r}{114\times p\times q}}$

= ${\displaystyle \frac{57}{114}pr}$

= ${\displaystyle \frac{1}{2}pr}$
