Carlos bought 20 pounds of vegetables at the farmer's market. 60% of the vegetables were organically grown. How many pounds of vegetables were not organically grown?

40% were not organic.

0.40 * 20 = ___

To find out how many pounds of vegetables were not organically grown, we first need to calculate the weight of the organically grown vegetables.

Step 1: Calculate the weight of the organically grown vegetables.
Given that 60% of the vegetables were organically grown, we can find the weight of the organically grown vegetables by multiplying the total weight of vegetables by 0.60.
Weight of organically grown vegetables = 20 pounds * 0.60 = 12 pounds.

Step 2: Calculate the weight of the vegetables that were not organically grown.
The weight of the vegetables that were not organically grown can be found by subtracting the weight of the organically grown vegetables from the total weight of vegetables.
Weight of vegetables not organically grown = Total weight of vegetables - Weight of organically grown vegetables.
Weight of vegetables not organically grown = 20 pounds - 12 pounds = 8 pounds.

Therefore, 8 pounds of vegetables were not organically grown.

To find the number of pounds of vegetables that were not organically grown, we need to calculate 40% of the total weight of the vegetables.

Step 1: Calculate the weight of the organically grown vegetables.
To find the weight of the organic vegetables, we can use the percentage given. 60% of the total weight is organically grown, so we need to find 60% of 20 pounds:
Organic vegetables = 60% * 20 pounds = 0.6 * 20 pounds = 12 pounds

Step 2: Calculate the weight of the non-organically grown vegetables.
To find the weight of the non-organic vegetables, we subtract the weight of the organic vegetables from the total weight:
Non-organic vegetables = Total weight - Organic vegetables = 20 pounds - 12 pounds = 8 pounds

Therefore, Carlos bought 8 pounds of vegetables that were not organically grown.
