Convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds how many kilograms are equal to 72 pounds round to the nearest tenth of a kilogram
A. 144
B. 3.27
C. 158.4
D. 32.7
To convert kilograms to pounds using the given proportion, we can set up the following equation:
1 kilogram = 2.2 pounds
To find how many kilograms are equal to 72 pounds, we can set up the proportion:
x kilograms = 72 pounds
Using the given proportion, we can set up the equation:
x/1 = 72/2.2
Now we can solve for x by cross-multiplying:
2.2x = 72
Dividing both sides by 2.2, we get:
x = 72/2.2
x ≈ 32.7
Therefore, the number of kilograms equal to 72 pounds, rounded to the nearest tenth of a kilogram, is 32.7.
The correct answer is D. 32.7.
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you can set up a proportion:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross-multiply and solve for x:
2.2x = 72
x = 72 / 2.2
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms.
Answer: D. 32.7
To convert kilograms to pounds using the given proportion, you can set up a proportion equation:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiply to solve for x:
2.2x = 1 * 72
2.2x = 72
x = 72 / 2.2
x ≈ 32.7
Therefore, 72 pounds is approximately equal to 32.7 kilograms.
The answer is D. 32.7
