Question

1. calculate: in an experiment, you need 250 grams of potting soil for each of 10 plant samples. how many kilograms of soil in total do you need?

Explanation:

Step1: Calculate total grams of soil

To find the total grams of soil needed, we multiply the amount per sample (250 grams) by the number of samples (10). So, $250 \times 10 = 2500$ grams.

Step2: Convert grams to kilograms

We know that 1 kilogram is equal to 1000 grams. To convert grams to kilograms, we divide the total grams by 1000. So, $\frac{2500}{1000} = 2.5$ kilograms.

Answer:

2.5 kilograms
