2 divided by 2/5 I may ask to show ur work
pashok25 [27]
1. I would first write it out as fraction
  2/1    divided by    2/5

2. When dividing fractions you need to find the reciprocal (opposite of or switched) of the fraction then multiply the two fractions together
2/1      divided by    5/2 <------- that's the reciprocal of 2/5

3. Now multiply
 
2     5        10
-  x  -   =     -   =     5

4. 5 is your answer! :)
1     2         2
