Q13:

A percent is a fraction where the denominator (i.e., the whole) is 100. In the diagram, a 100-centimeter ruler has been used to represent the whole.

What is the length of the shaded part in centimeters? What percent of the ruler is it?

  • A 7 0 , 7 5 % c m
  • B 2 5 , 2 5 % c m
  • C 7 5 , 7 5 % c m
  • D 3 0 , 3 0 % c m
  • E 4 0 , 4 0 % c m

If now we use meter as a length unit and the ruler is one meter long, what is the length of the shaded part in meters?

  • A 0.3 m
  • B 0.75 m
  • C 0.7 m
  • D 0.25 m
  • E 0.4 m

The ratio of the length of the shaded part to that of the whole ruler can be expressed as a fraction, a percent (which is a fraction where the denominator is 100), or as a decimal. In the latter case, the decimal can be interpreted as the length of the shaded part when the whole is 1. Give this ratio as a decimal.
