Question

Line segment AB represents 500%, Find the length of a line segment which is 100% (whereas AB = 125cm)

  1. 125cm
  2. 45cm
  3. 25cm
  4. 50cm

Hint:

500% is 5 times of 100%. So to find 100%, divide by 5.

The correct answer is: 25cm


    Length of line segment AB = 125cm
    This 125 cm = 500% (1)
    To find the length of a line segment which is 100%, divide equation 1 by 5 on both sides.
    125 over 5 c m equals space fraction numerator 500 percent sign over denominator 5 end fraction space
25 c m space equals space 100 percent sign
    Thus, the length of line segment which is 100% is 25cm.

    Alternatively,
    By cross multiplication,
    500% = 125cm
    100% = fraction numerator 125 c m space cross times 100 percent sign over denominator 500 percent sign end fraction space equals 25 c m
