Answer 1

12. Given the expression :

`3(6)/(12)*(7)/(12)=?`

Convert the mixed number to fraction :

`3(6)/(12)=3(6)/(6\cdot2)=3(1)/(2)=(2\cdot3+1)/(2)=(7)/(2)`

Then find the result of the multiplication:

`3(6)/(12)*(7)/(12)=(7)/(2)\cdot(7)/(12)=(49)/(24)`

Convert the result from fraction to a mixed number:

`(49)/(24)=(2\cdot24+1)/(24)=2(1)/(24)`

So, the answer is :

`2(1)/(24)`
