This is percent of change

15 yards to 18 yards

100 acres to 140 acres

$15.60 to $11.70

125 centimeters to 87.5 centimeters

1.6 hours to 0.95 hour

and

132 days to 125.4 days

I was just wondering because so I could check my answers

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%
