To find the difference in their weights in kilograms, we first need to convert their weights from pounds to kilograms.
Donnie weighs 188 pounds, so his weight in kilograms is 188 / 2.2 = 85.45 kg.
Ronnie weighs 165 pounds, so his weight in kilograms is 165 / 2.2 = 75 kg.

Therefore, the difference in their weights in kilograms is 10.45 kg.
To find the difference in their weights in kilograms, we first need to convert their weights from pounds to kilograms.
Donnie weighs 188 pounds.
So, Donnie's weight in kilograms is 188 / 2.2 = 85.45 kg (rounded to the nearest hundredth).
Ronnie weighs 165 pounds.
So, Ronnie's weight in kilograms is 165 / 2.2 = 75 kg (rounded to the nearest hundredth).
The difference in their weights is Donnie's weight minus Ronnie's weight:
85.45 kg - 75 kg = 10.45 kg (rounded to the nearest hundredth).
Therefore, the correct answer is:
The difference in their weights is 10.45 kg.
To find the difference in their weights in kilograms, we first need to convert their weights from pounds to kilograms.
Donnie weighs 188 pounds. To convert this to kilograms, we divide by the conversion factor of 2.2:
188 pounds / 2.2 pounds/kg = 85.45 kilograms (rounded to the nearest hundredth)
Ronnie weighs 165 pounds. Similarly, we divide by 2.2 to convert to kilograms:
165 pounds / 2.2 pounds/kg = 75 kilograms (rounded to the nearest hundredth)
To find the difference in their weights, we subtract Ronnies weight from Donnie's weight:
85.45 kg - 75 kg = 10.45 kg (rounded to the nearest hundredth)
Therefore, the difference in their weights in kilograms is 10.45 kg.
