Question

A library finds that borrowing reference books between libraries are 18 over 10 of what it was 10 years ago. Write this fraction as a percent.

  1. 10%    
  2. 18%    
  3. 1800%    
  4. 180%    

Hint:

To write a fraction as percent either convert it into decimal and then multiply by 100 and add symbol % or multiply the fraction by 100 and find the value directly.

The correct answer is: 180%

18 over 10 space space equals space 1.8
N o w space c o n v e r t space d e c i m a l space i n t o space p e r c e n t space b y space m u l t i p l y i n g space b y space 100 space a n d space a d d i n g space t h e space s y m b o l space percent sign.
1.8 space cross times 100 space equals space 180 percent sign
