Final answer:
To find the total weight of the fruit in grams, we need to convert the given weights to grams and then add them together.
Step-by-step explanation:
To find the total weight in grams, we need to convert all the given weights to grams and then add them together. 1 kilogram is equal to 1000 grams, so we can convert the given weights as follows:
- 1.5 kilograms of oranges = 1.5 * 1000 = 1500 grams
- 150 grams of grapes = 150 grams
- 15000 centigrams of apples = 15000 / 100 = 150 grams
Now, we can add the weights together: 1500 grams + 150 grams + 150 grams = 1800 grams. Therefore, Josh bought 1800 grams of fruit in total.
