Question

If 2.2 pounds = 1 kilogram and Mary weighs 120 pounds, how much does she weigh in
kilograms?

Answer 1

Given:

2.2 pounds = 1 kilogram

Weight of Mary = 120 pounds.

To find:

The weight of Marry in kilograms.

Solution:

We have,

2.2 pounds = 1 kilogram

Using this conversion, we get

1 pound =
`(1)/(2.2)` kilogram

120 pound =
`(1)/(2.2)* 120` kilogram

=
`(120)/(2.2)` kilogram

`\approx 54.54` kilogram

Therefore, the weight of Mary is about 54.54 kilograms.
