Frank had a 1.5kg bag of potting soil. He used 420g of soil to pot a plant. How many kilograms of soil are left in the bag? Write your answer with two decimal places.

Respuesta :

Answer:

1.08kg

Step-by-step explanation:

1.5kg= 1500g

If he used 420g then:

1500-420 = 1080g

Simplify 1080g to kg

1080/1000= 1.08kg
