The table below shows the number of children, c, to each childcare worker, w. Based on the information in the table, which of the following statements is not correct

I'll show  you the percent of change
15 yards to 18 yards
 => 18 - 15 = 3 yards 
=> 3 yards / 15 = .2 * 100% = 20%

100 acres to 140 acres
 => 140 - 100 = 40 acres 
=> 40 /100 = 0.4 * 100% = 40%

$15.60 to $11.70 
=> 15.60 - 11.70 = 3.6 dollars 
=> 3.6 / 15.60 = 0.25 * 100% = 25% 

125 centimeters to 87.5 centimeters
 => 125 cm - 87.5 cm = 37.5 cm  
=> 37.5 / 125 = 0.3 * 100% = 30%

1.6 hours to 0.95 hour 
=> 1.6 - .95 = 0.65 
=> 0.65 / 1.6 = 0.41 * 100% = 41%

and 132 days to 125.4 days  
=> 132 - 125.4 = 6.6 
=> 6.6. / 132 = 0.05 * 100% = 5%
