The best way to multiply a whole number by a fraction is to tackle the problem in two parts. First you multiply the number by the numerator (top) of the fraction. Second you divide the number by the denominator (bottom) of the fraction.
For example, if I wanted to work out 25 x 4/10
I would do 25x4, which = 100
Then I would do 100/10, which = 10, so the answer is 10.
This is only the mental method though. When writing down on paper you would do this all in one step, as 25 x 4/10 = 10.
