71/7*52/5*2/35

Question

Multiplying mixed fractions or numbers..show working out

Answer 1

7 1/7 x 5 2/5 x 2/35

Converting these to improper fractions

= (7 x 7) + 1      5 * 5 + 2        2 
       7        x           5         x  35

= 50      27     2
   7   x  5    x 35

Unless you like dealing with large numbers, factorize these first:

= 2 x 5 x 5   3 x 3 x 3      2
      7           5     x  5 x 7
      
= 2   3 x 3 x 3    2
  7  x    1     x  7

= 108
    49      

= 2 10/49
