Donnie and Ronnie are trying to figure out how much they weigh in kilograms. They discover that 1 kilogram equals 2.2 pounds. Donnie weighs 188 pounds, and Ronnie weighs 165 pounds. What is the difference in their weights in kilograms? Round to the nearest hundredth.(1 point)
To find the weight difference in kilograms, we 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 per kilogram = 85.45 kilograms
Ronnie weighs 165 pounds. To convert this to kilograms, we divide by the conversion factor of 2.2:
165 pounds / 2.2 pounds per kilogram = 75 kilograms
Thus, the weight difference in kilograms is:
85.45 kilograms - 75 kilograms = 10.45 kilograms.
Rounded to the nearest hundredth, the weight difference in kilograms is approximately 10.45 kilograms.
To find the weights of Donnie and Ronnie in kilograms, we need to convert their weights from pounds to kilograms using the conversion factor of 1 kilogram = 2.2 pounds.
First, we'll convert Donnie's weight:
Donnie weighs 188 pounds.
To convert this to kilograms, we divide his weight by the conversion factor:
188 pounds / 2.2 kilograms per pound ≈ 85.45 kilograms (rounded to the nearest hundredth).
Next, we'll convert Ronnie's weight:
Ronnie weighs 165 pounds.
To convert this to kilograms, we divide his weight by the conversion factor:
165 pounds / 2.2 kilograms per pound ≈ 75 kilograms (rounded to the nearest hundredth).
To find the difference in their weights:
85.45 kilograms - 75 kilograms ≈ 10.45 kilograms (rounded to the nearest hundredth).
Therefore, the difference in Donnie and Ronnie's weights in kilograms is approximately 10.45 kilograms.
To find out the difference in Donnie and Ronnie's weights in kilograms, we need to convert their weights from pounds to kilograms using the given conversion rate of 1 kilogram equals 2.2 pounds.
First, let's convert Donnie's weight from pounds to kilograms:
Donnie's weight in kilograms = (Donnie's weight in pounds) / (conversion rate)
Donnie's weight in kilograms = 188 pounds / 2.2
Donnie's weight in kilograms ≈ 85.45 kilograms (rounded to the nearest hundredth)
Next, let's convert Ronnie's weight from pounds to kilograms:
Ronnie's weight in kilograms = (Ronnie's weight in pounds) / (conversion rate)
Ronnie's weight in kilograms = 165 pounds / 2.2
Ronnie's weight in kilograms ≈ 75 kilograms (rounded to the nearest hundredth)
Now that we have both Donnie and Ronnie's weights in kilograms, we can find the difference by subtracting Ronnie's weight from Donnie's weight:
Difference in weights in kilograms = Donnie's weight in kilograms - Ronnie's weight in kilograms
Difference in weights in kilograms = 85.45 kilograms - 75 kilograms
Difference in weights in kilograms ≈ 10.45 kilograms (rounded to the nearest hundredth)
Therefore, the difference in Donnie and Ronnie's weights in kilograms is approximately 10.45 kilograms.
