Answer 1

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.

To find the difference in their weights, we subtract Ronnie's weight from Donnie's weight: 85.45 kg - 75 kg = 10.45 kg.

Therefore, the difference in their weights in kilograms is 10.45 kg.
