Final answer:
The problem provided lacks context to determine what fraction of a crop has gone to market. It does present information on the weight of fruits purchased at a market, which total 1800 grams after converting units to grams.
Step-by-step explanation:
The question appears to revolve around understanding how to sum fractions and convert units of measurement to determine the total weight of fruit purchased at the market. However, the provided information does not give any detail about a crop or fractions of a crop sold at market. Without context or additional data related to a farmer's crop sales, it's not possible to accurately answer which fraction of the crop has gone to market. Instead, let's address the calculations involving fruit weights that were mentioned. Josh bought 1.5 kilograms of oranges, 150 grams of grapes, and 15,000 centigrams of apples.
Firstly, we need to convert all weights into the same unit, which will be grams in this case:
- 1.5 kilograms of oranges is equal to 1500 grams (since 1 kilogram = 1000 grams).
- 150 grams of grapes are already in the correct unit.
- 15,000 centigrams of apples need to be converted to grams. Since 1 gram = 100 centigrams, this is equal to 150 grams.
Adding all the weights together, we get:
1500 grams (oranges) + 150 grams (grapes) + 150 grams (apples) = 1800 grams
Therefore, Josh bought a total of 1800 grams of fruit at the market.
