Write and solve a proportion to complete the statement. Round your answer to the nearest hundredth.
90 lb ≈ kg
I am having trouble even understanding how to do this?
Even after the explaining, I am still confused. How do you find x?
1 kg = 2.20462 pounds
1/2.20462 = x/90
Cross multiply and solve for x.
To solve this proportion, we need to convert pounds (lb) to kilograms (kg). The conversion factor is approximately 2.20462 pounds in 1 kilogram.
Let's set up the proportion using the formula:
pounds / conversion factor = kilograms
In this case, we have 90 pounds and we want to find the equivalent value in kilograms. So the proportion will be:
90 lb / 2.20462 lb ≈ kg
To solve for kg, we cancel out the lb units by dividing:
90 / 2.20462 ≈ kg
Using a calculator, we find:
kg ≈ 40.82
Rounding to the nearest hundredth, the approximate value is 40.82 kg.
