Final answer:
Josh bought a total of 1800 grams of fruit at the farmer's market, after converting the weights of oranges, grapes, and apples into grams.
Step-by-step explanation:
To calculate the total weight of the fruit that Josh bought at the farmer's market, we need to convert all quantities into the same unit, which will be grams in this case. Josh bought 1.5 kilograms of oranges, 150 grams of grapes, and 15,000 centigrams of apples.
- 1.5 kilograms of oranges = 1500 grams
- 150 grams of grapes = 150 grams
- 15,000 centigrams of apples = 150 grams
We add these amounts together to get the total grams of fruit Josh bought:
1500 grams (oranges) + 150 grams (grapes) + 150 grams (apples) = 1800 grams
Therefore, Josh bought a total of 1800 grams of fruit.
