Question

1/2 times a for a = 3/10

Answer 1

Since you are multiplying a fraction with another, all you have to do is cross multiply. First, set it up:
1    3
_    _                    
2   10
Multiply straight across and that would equal 3/20. Since it cannot be simplified, 3/20 is the final answer. Hope this helped. Cheers, mimiisawesome5
