Answer

Waialeale has the greater average rainfall by 46 inches.

Work Step by Step

The rainfall in Debundscha is 10,280 mm. Since 1 cm = 10 mm, we need to move the decimal place 1 place to the left to convert from units of mm to units of cm. $10,280~mm = 1028~cm$ We can convert the rainfall in Debundscha from units of centimeters to units of inches. $1028~cm = \frac{1028~cm}{1}\times \frac{1~in}{2.54~cm} = 405~in$ The rainfall in Debundscha is 405 inches. The rainfall in Waialeale is 451 inches. Waialeale has the greater average rainfall by 46 inches.
