Final answer:
Josh bought a total of 1,800 grams of fruit at the farmer's market, after converting each weight to grams and summing them up. Additionally, 32 ounces is greater than 30 ounces, since it equates to 2 pounds.
Step-by-step explanation:
Josh's purchase at the farmer's market is a multi-step math problem requiring unit conversion and addition to find the total weight of fruit he bought in grams. Starting with 1.5 kilograms of oranges, we convert this to grams by multiplying by 1,000 (as there are 1,000 grams in a kilogram), resulting in 1,500 grams. In dealing with the 150 grams of grapes, no conversion is needed as it is already in the desired unit of grams. Finally, the 15,000 centigrams of apples must be converted into grams; since there are 100 centigrams in a gram, we divide 15,000 by 100 to get 150 grams of apples. Adding these amounts together—1,500 grams of oranges, 150 grams of grapes, and 150 grams of apples—gives us the total weight of fruit Josh bought, which is 1,800 grams.
To compare weights such as 32 ounces and 30 ounces, we should know that 1 pound is equal to 16 ounces. Therefore, 32 ounces is equivalent to 2 pounds. When comparing these weights, we see that 32 ounces is greater than 30 ounces. Understanding these conversions and comparisons is crucial in various real-life situations, such as shopping or cooking, where different units of measurement are commonly used.
