Answer:

a)16 b)5c)31/12

Step-by-step explanation:

we need to divide so we will multiply by the reciprocal of the second number

Answer 2

Step-by-step explanation:

To divide, write the reciprocal of the second no. or the to be divided with and multiply them.

a) 12÷3/4

= 12 x 4/3 [  12 can be cancelled by 3]

= 4x4

= 16

B) 8/4÷2/5

= 8/4 x 5/2 [ cancelling 8 by 2]

= 4/4 x 5 [ cancelling 4 by 4]

= 1 x 5

= 5

C) 3 1/5÷12/5​ [ convert mixed fraction to improper fraction ]

=16/5 ÷12/5​

= 16/5 x 5/12 [ cancelling 5 by 5 ]

=16/12 [  cancelling both 16 and 12 by 4 ]

= 4/3

= 1  1/3
