On dividing 57p²qr by 114pq, we get
(a) 1/4 pr
(b) 3/4 pr
(c) 1/2 pr
(d) 2pr

Solution:

Correct option is (c ).

Given, divide 57p²qr by 114pq

= 57p²qr / 114pq

= 57 × p × p × q × r / 57 × 2 × p × q

Canceling the common terms,

= 1pr / 2 or (1/2)pr

✦ Try This: On dividing 180a²b²c² by 5ab, we get (a) 36, (b) 36ab, (c) 36abc, (d) 36abc²

Correct option is (d)

Given, divide 180a²b²c² by 5ab

= 180a²b²c²/ 5ab,

= 5 × 36 × a × a × b × b ×c × c / 5 × a × b

= 36abc²
