Final answer:
Kassidy's baby boy weighed 6⅙ pounds at birth and now weighs 2⅙ times his birth weight, which calculates to be 14⅙ pounds.
Step-by-step explanation:
To find Kassidy's baby boy's current weight, we must first convert his birth weight into an improper fraction, then multiply by the factor that represents the increase in weight. Kassidy's baby boy weighed 6⅙ pounds at birth. As an improper fraction, this translates to ⅙ pounds (6×9 = 54, 54 + 1 = 55). Therefore, his birth weight is ⅙ pounds.
Next, we are told that he now weighs 2⅙ his birth weight. To calculate this, we simply multiply the birth weight by 2⅙:
⅙ pounds (birth weight) × 2⅙ (current weight factor) = ⅙ pounds × ⅙ × ⅙ pounds
First, we convert 2⅙ into an improper fraction, which is ⅒. Now, we multiply the two improper fractions:
⅙ pounds × ⅒ = ⅒ pounds.
Finally, we calculate this product:
55 × 12 = 660, and 660 divided by 45 is 14⅙ pounds.
Therefore, Kassidy's baby boy currently weighs 14⅙ pounds.
