Question

What's 3 over 10 times 1over 6 ?

Answer 1

$\frac{3}{10}$×$\frac{1}{6}$
To multiply, you multiply across. So it would be 3×1=3 and 10×6=60
Which will result in $\frac{3}{60}$ but in order to simplify it, you find a common factor. The common factor is 3. 3÷3=1 and 60÷3=20
The answer is $\frac{1}{20}$

Answer 2

 3      1
--- x --- = 
10     6

You cross out 3 and six and change them into 1 and 2 to simplify 

 1      1      1
--- x --- = ---
10     2      20
