Ответ:
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%
