Convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds. How many kilograms are equal to 72 pounds?
A. 3.27
B. 144
C. 32.7
D. 158.4
To convert kilograms to pounds, you can use the proportion 1 kilogram = 2.2 pounds.
Let x be the number of kilograms equal to 72 pounds.
Setting up the proportion: 1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Cross multiplying, we get 1 kilogram * 72 pounds = 2.2 pounds * x kilograms
Simplifying, we have 72 = 2.2x
Dividing both sides by 2.2, we get x = 72 / 2.2
Calculating, x ≈ 32.73
So the number of kilograms equal to 72 pounds is approximately 32.73.
Therefore, the answer is A. 32.73
To convert kilograms to pounds using the proportion 1 kilogram = 2.2 pounds, you can set up a proportion with the given information:
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
To find the value of x, you can cross-multiply and solve for x:
(1 kilogram) * (72 pounds) = (2.2 pounds) * (x kilograms)
72 = 2.2x
Divide both sides of the equation by 2.2 to isolate x:
x = 72 / 2.2
Calculating this gives:
x ≈ 32.7272727273
So, 72 pounds is approximately equal to 32.73 kilograms.
The correct answer is:
C. 32.7
To convert kilograms to pounds using the given proportion, you need to divide the number of pounds by 2.2. Let's apply this to the given question.
Step 1: Set up the proportion
1 kilogram / 2.2 pounds = x kilograms / 72 pounds
Step 2: Cross multiply
2.2 pounds * x kilograms = 1 kilogram * 72 pounds
Step 3: Solve for x
2.2x = 72
Divide both sides of the equation by 2.2:
x = 72 / 2.2 ≈ 32.7
Therefore, 72 pounds is equal to approximately 32.7 kilograms.
The correct answer is C. 32.7.
