Question

A steel rod of length 12 m is cut into small rods of length fraction numerator 1 over denominator 4 end fractionm. How many small rods can be cut?

  1. 24    
  2. 48    
  3. 36    
  4. 3    

Hint:

To find the number small rods that can be cut from a long rod ,we divide the total length of the long rod divided by length of each small rod.

The correct answer is: 48


    The length of a small rod = 1 fourth m; The length of a long rod = 12 m
    The number of small rods equals space 12 divided by 1 fourth
    We can multiply the reciprocal of the denominator with the numerator to find the value of the problem.
    equals space 12 space cross times space 4 over 1 space4 over 1 is the reciprocal of 1 fourth)
    = 48
    Therefore, The number of small rods that can be divided is 48.
