Toby opened a new bag of dog food that had a mass of 25 kg. He poured 10 kg of the food into one container and 6 kg into another container. How many grams of dog food did Ben have left in the bag?

Answer 1

There are 25,000 grams in 25 kg. Toby poured 10 kg (10,000 grams) into one container and 6 kg (6,000 grams) into another container.

So, Toby used a total of 10,000 + 6,000 = 16,000 grams of dog food.

Therefore, Ben had 25,000 - 16,000 = 9,000 grams of dog food left in the bag.
