6 x 3 1/2 = 21
Multiplying fractions: 

  numerator   x  numerator  = answer in lowest term
denominator x denominator

Convert the mix fractions to improper fractions, then multiply:
1) [tex]1 \frac{1}{3} = \frac{4}{3} [/tex]
    [tex](3)(\frac{4}{3})  = 4[/tex]

2) [tex]2 \frac{1}{2} = \frac{5}{2} [/tex]
    [tex](4)(\frac{5}{2}) =10[/tex]

3)  [tex]3 \frac{1}{2} = \frac{7}{2} [/tex]
     [tex](6)(\frac{7}{2}) = \frac{42}{2} [/tex]  or 21
