Explanation

We will drop the % symbol and divide each given number by 100 by moving the decimal point 2 places to the left.

Recall to find the quotient of a decimal and 10, 1,000, and so on, move the decimal point to the left the same number of places there are zeros in the power of 10.

Solution

1. From the graph, we see that the percent market share for the American Idol website is 32.86%.  To write this percent as a decimal, we proceed as follows.
   • Drop the % symbol and divide 32.86 by 100 by moving the decimal point 2 places to the left.
     • 32.86% = .3286
   • Write a zero to the left of the decimal point
     • = 0.3286
   • 32.86%, written as a decimal, is 0.3286
2. From the graph, we see that the percent market share for the Deal or No Deal website is 4.52%.  To write this percent as a decimal, we proceed as follows
   • Drop the % symbol and divide 4.52  by 100 by moving the decimal point 2 places to the left.  This requires that a placeholder zero (shows in blue) by inserted in front of the 4.
     • 4.52% = .0452
   • Write a zero to the left of the decimal point
     • = 0.0452
   • 4.52%, written as a decimal, is 0.0452
