Question

Dr. O is playing in her garden again She needs 1 kg of potting soil for her plants. She has 750 g. How much more does she need? Explain your answer.

Answer 1

She needs 250 g more of potting soil.

Step-by-step explanation:

Write 1 kg in grams, so you can compare the quantities in the same units: 1 kg = 1000 g

Then, since she has 750 g, she needs 1000 g - 750 g = 250 g to complete her task.
