Final answer:
Josh bought a total of 1800 grams of fruit.
Step-by-step explanation:
To find the total number of grams of fruit Josh bought, we need to convert the given measurements to grams and then add them together.
Given:
- 1.5 kilograms of oranges = 1.5 kg x 1000 g/kg = 1500 g
- 150 grams of grapes = 150 g
- 15,000 centigrams of apples = 15,000 cg x 0.01 g/cg = 150 g
Adding these amounts together, Josh bought a total of 1500 g + 150 g + 150 g = 1800 g of fruit.
