Question

The weight of a full steel bead tire is approximately 800 grams, while a lighter wheel weighs only 700 grams. What is the weight of each tire in pounds? There are 453.592 grams in one pound. Round answers to 2 decimal places.

800grams=?lbs

700grams=?lbs

Answer 1

800= about 1.76 lbs

700= about 1.54 lbs

(there are about 453.5 grams in a pound

Answer 2

we know that

`1\ pound=453.592\ grams`

so by proportion

convert grams to pounds

Part a)
`800\ grams`

`(1)/(453.592)(lb)/(g) =(x)/(800)(lb)/(g)\\ \\x*453.592=800\\ \\x=800/453.592`

`x=1.76\ lbs`

therefore

the answer Part a) is

`1.76\ lbs`

Part b)
`700\ grams`

`(1)/(453.592)(lb)/(g) =(x)/(700)(lb)/(g)\\ \\x*453.592=700\\ \\x=700/453.592`

`x=1.54\ lbs`

therefore

the answer Part b) is

`1.54\ lbs`
