Question

2 3/5 divides by 1 1/25

Answer 1

2 3/5            13/5         
----------  =  ----------- 
1 1/25           26/25  

Let's multiply 13 and 5 by 5, so that 13/5 has the new denominator 25, to match the denominator in 26/25:

5(13)
--------
  5(5)

Dividing this by 11/25 would be expressed as


----------
11
-----
 25

Invert the divisor and then multiply:

65     25
--- * -------            This reduces to 65/11 (answer)
25     11
