To find the total weight of the vegetables in the baskets, you can multiply the number of baskets by the weight of vegetables in each basket.
Lars has 10 baskets and each basket contains \(1 \frac{1}{2}\) lbs of vegetables. First, convert \(1 \frac{1}{2}\) to an improper fraction:
\[ 1 \frac{1}{2} = \frac{2}{2} + \frac{1}{2} = \frac{3}{2} \text{ lbs} \]
Now, multiply the number of baskets by the weight of vegetables in each basket:
\[ 10 \times \frac{3}{2} = \frac{30}{2} = 15 \text{ lbs} \]
Since 15 is already a whole number, we can express it as a mixed number:
\[ 15 = 15 \frac{0}{1} \]
So, the total weight of all the vegetables in the baskets is:
\[ 15 \text{ lbs} \]
Therefore, the total weight of all the vegetables in the baskets is 15 lbs.
