Question

Kim buys 6 pounds of apples.

What is the weight of the apples in kilograms?
Round to the nearest tenth, if necessary.

Answer 1

Answer: 2.7 kg

1 kilogram (kg) = 2.204623 pounds (lb)

`(6 lb)/(1)` ×
`(1 kg )/(2.204623 lb)` = 2.721553753 kg

You place 1 kg over 2.204623 lb since they are equal. In the above equation, the pounds (lb) cancel out since one is in the numerator (the number on top of the fraction) and one is in the denominator (the number on the bottom of the fraction). You multiply 6 by the 1 in the numerator and multiply the 1 in the denominator by 2.204623. This turns the equation into:

`(6 kg)/(2.204623)` =2.721553753 kg

You divide 6 by 2.204623 to get 2.721553753

To round to the tenths place, you include only the first number to the right of the decimal, which is 7. Since the number to the right of the 7 is less than five, it stays 7. If it were five or bigger, 7 would turn into 8.

The answer: 2.7 kg
