Question

James has 14,500 g of sand in his sandbox. He brings home another 7,400 g of sand from the beach to add to his sandbox. How many kilograms does James have in his sandbox now?

Answer 1

Answer:

21.9 kilograms

Step-by-step explanation:

To find the total amount of sand, We need to add the new to the old. Lets have x be the total amount of sand.

14500+7400=x

Add them up

21900=x

The total amount of sand is 21900 grams

Now to find the kilograms we need to divide this number by 1000. Let y be the kilogram amount.

21900/1000=y

divide

21.9=y

There are 21.9 kilograms
