Answer

$0.25\text{ lb}\approx 113.40\text{ g}$

Work Step by Step

The difference between the lungs is: $1.5\text{ lb}-1.25\text{ lb}=0.25\text{ lb}$ If we want to convert from pounds to grams, we have to consider the following conversion rate: $1\text{ lb}\approx 453.592\text{ g}$ We multiply both sides by $0.25$ in order to get the answer to the question: $0.25\text{ lb}\approx 0.25\times 453.592\text{ g}\approx 113.398\text{ g}$ By rounding it to two decimal places we get: $0.25\text{ lb}\approx 113.40\text{ g}$
