Find the product of 3 times 3/10

3     3     9
_ x __ =___  
1    10     10
first, change 3 to 3/1 to make multiplying easier. then multiply both fractions(3*3=9,1*10=10)  and you get 9/10! this can not be simplified.  

The first thing to do is convert 3 into a decimal.  The equation is now 3/1 X 3/10.  Now you need to find the lowest common multiple of 1 and 10, which is 10.  10 / 1 = 10.  3 X 10 = 30.  The question is now 30/10 X 3/10.  30 X 3 = 90.  10 X 10 = 100.  3 X 3/10 = 3/1 X 3/10 = 30/10 X 3/10 = 90/100 = 9/10.
