Question

2. A stone is an English measure of weight. There are 14 pounds in 1 stone and 2.2 pounds in 1 kilogram. A certain person weighs 9 stone.

(a) If you wanted to convert the person’s weight to kilograms, what conversion factor should you use? Round the conversion to the nearest hundredth. Show your work.

(b) What is the person’s weight in kilograms rounded to the nearest tenth?

Answer 1

The answer to your question is 57.3 kg

Explanation:

a)

`X stones (14 pounds)/(1 stone) (1 kilogram)/(2.2 pounds)`

=
`(14)/(2.2)`

= 6.36 X stones

b) Weight = 6.36 (x)

x = 9 stones

Weight = 6.36 (9)

= 57.3 kg
