A nice thing to know is ur times table.
But...
12*1-12
*2=24
*3=36
*4-48
then (48*3) = 144
144/4 = 36
that is one way to do it mentally if you are also no good at fractions!
hope it helps :)

12*4 is easy. If you remember the multiplication table. Hope you did. 12*4 would be 48. I don't get what you mean 3/4. Product is when you multiply. 3/4 is weather you divide it or what the percentage of the fraction is. Which would be 75%
thank yo
