Solution:

3/5 ÷ 12

= 3/5 ÷ 12/1

= 3/5 × 1/12

= (3 × 1)/(5 × 12)

= 3/60

= 1/20

Step I: discover the reciprocal of the entirety number and multiplywith the fractional number as usual.

Step II: refer the product in its shortest terms.


= 5/7 ÷ 10/1

= 5/7 × 1/10

= (5 × 1)/(7 × 10)

= 5/70

Step I: discover the mutual of the totality number and multiplywith the fountain number together usual.

Step II: refer the product in its lowest terms.


Solution:

7/8 ÷ 1/5

= 7/8 × 5/1

= (7 × 5)/(8 × 1)

= 35/8

= 4 3/8

= 11/4 × 3/5

= (11 × 3)/(4 × 5)

= 33/20

= 1 13/20

Express the mixed numbers as improper fractions and also multiplyas usual.


Solution:

2  4/17 ÷ 1  4/17

= 38/17 ÷ 21/17

= 38/17 × 17/21
