Solution:

3/5 ÷ 12

= 3/5 ÷ 12/1

= 3/5 × 1/12

= (3 × 1)/(5 × 12)

= 3/60

= 1/20

Tip I: Find the reciprocal of the entirety number and multiplywith the fractional number as usual.

Step II: Expush the product in its lowest terms.


= 5/7 ÷ 10/1

= 5/7 × 1/10

= (5 × 1)/(7 × 10)

= 5/70

Step I: Find the reciprocal of the totality number and multiplyvia the fractional number as usual.
